On cars without full brightness control, any brightness setting above 50% will set the light to ON and otherwise it will be OFF.

The minimum on-time for boolean light channels to produce light is 15ms, although human eyes will have a hard time seeing anything this short! Minimum on-time or off-time of 100ms generally makes the show more pleasing to look at.

Some lights on Cybertruck have full brightness control. Their brightness always corresponds to the value set in xLights.

I think this lighting model works best in simulating outdoor light. I set my direct light to be probably a pastel yellow to model sunlight and set the ambient light to a pastel blue to model refracted light from the blue sky. I then add them so that even the areas in diffuse light also get the ambient light. But the dark side of objects only get the ambient light.

Reflected light in the real world is almost never white. But this depends on the situation of course. Is the light source it came from even white? If the object it’s reflecting off of has pigment it’s probably going to subtract part of the light unevenly meaning the light that comes off it will be colored. That’s why we perceive colored object as having a color.

Within each of the following 3 categories, transitions that happen at the same timestamp will only contribute 1 command towards the overall limit. Therefore, within these categories, it is recommended to align transitions at the same timestamp as much as possible.

A Python validator script is provided to help check if your custom light show sequence meets these limitations, without needing a Tesla vehicle.

But ambient light will not make things look 3D; by itself it only gives you a silhouette. The texture will help make it look 3D by itself. But without a texture (and somewhat even with the texture), the diffuse light is what makes objects look 3D. It’s also a big part of what makes bump/normal mapping work. It’s mostly the diffuse light that is affected by the normal map. (Normal maps give a direction for every pixel rather than for the entire surface which is then used in diffuse and specular lighting calculations.)

Custom ramp durations can be achieved using 'Value Curves'. The menu is opened when clicking the green arrow next to the brightness slider. To create a basic ramp, select 'Ramp' from the drop-down list and set the start/end duration to 0%/100%. The light will reach 0%/100% brightness at the end of the 'On' effect.

When you add textures, this changes things a bit because you may light the object with the texture. I think the best way to go is to multiply the texture color with these other light sources so that the texture is given the color of the light sources. For example, if you multiply black (the dark side of the object) times any color including the texture color, you get black. Multiply white times that same color and you get the color rather than white. Multiply a color times the texture color and the texture color will be tinted.

Left inner main beam, Turn on; 2000 ms, effect duration 1s: causes the light to ramp from 0% to 50% intensity over 1s, then instantly turn off (because of the empty timeline).

thanks for your reply, i’ll take a look at your video tutorials and thx for the info about the spec texture, first i thought these are the Ks values :doh:

All old .xsq and .fseq files are fully compatible with this light show update. You can edit older .xsq files instantly without converting them. Keep in mind that there is no backwards compatibility, once you save them, you won't be able to open them with the old project folder anymore.

Some channels can have a slow ramp in the intensity during turn-on or turn-off, to create graceful visual effects. Some even allow for full brightness control:

Any transition of a light or closure contributes towards this command limit. Eg, turning a light on and off is 2 transitions.

For more information on the workflow of creating xLights sequences, please use existing online resources. The rest of these instructions contain Tesla-specific information for show creators.

For Idle, Open, Close, and Stop, there is no minimum xLights effect duration in order for the command to take effect. For example, the following sequence has a liftgate open command with duration of only 1s ahead of the dance that comes later, and this is sufficient to open the liftgate all the way:

Diffuse light has a direction that it shines in represented by a normal. A surface that faces directly into that direction gets 100% of that light color. If it faces 90 degrees away or more, it will get no diffuse light and will presumably be pitch black. And if it faces some angle in between it will get a percentage of the diffuse light, which is primarily what makes objects look 3D. But shadows in the real world are almost never pitch black. They are usually lit up by reflection off surfaces such as walls or even the blue sky. That’s why shadows outdoors tend to have a blue tint; they are lit by the blue sky since the direct sunlight cannot reach those spots - but that doesn’t mean there is no light there.

Race Sport Lighting has over 12+ lines of LED Light bars available from starter light bars to professional grade high performance light bars.

Diffuse lighting meaningin physics

In this example, two lights will be turned on and off again, one will be ramped and turn off again, and one closure will start moving. Because they're aligned, this effect only counts as two transitions - One at the beginning, and one at the end of the effect.

The following tables and images help show which channels are controlled on each car. Some vehicles have lights that do not exist, or have multiple lights driven by the same control output - see notes in Light channel mapping details for this information.

Note that the previewed Tesla Model S combined with the Cybertruck include the superset of lights and closures that are needed for all supported vehicles, and should be used to generate shows for all vehicle types. See light channel locations for information about where the lights are on each vehicle.

Place an 'On' Effect using the shortcut F. Lights can be set to a steady-state brightness setpoint between 0% and 100% intensity using the 'Brightness' slider in the 'Colors' window.

White is a good place to start for specular. I’ve been making my specular highlights the color of the diffuse light source because “presumably” that’s where the specular light supposedly came from. And as I said, I often try to make my diffuse light “sun” colored rather than white. But I’m taking a 3D modeling course right now and one of the things that came up is the other day is specular maps. There you control the specular value for every pixel of the object individually. So, one part of the object can be shiny while the part next to it may be dull. A metal belt buckle on a leather belt might be an example. But sometimes artists use colored specular maps to give a separate color to the specular highlight than the surface color given by the texture. Sometimes they don’t; they just have a shininess value in the specular map but no color information.

In this example, Channel 4 & 6 ramp up and ramp down again. Notice how Channel 6 has the Turn On; Instantly effect while Channel 4 defines the effect to be Turn On; 1000ms for both channels.

What is diffused light for plants

To command a light to turn on or off and follow a ramp profile, place the effect with the corresponding keyboard shortcut:

Diffuse light is light that comes from a large light source, like the sun. The light comes from the same direction no matter where you are in the scene. So, this doesn’t work for a street lamp at night, for example. But on a sunny day everything in the neighbourhood will be lit up from the same direction because the sun is such a huge light source that basically everything for many miles will be lit up the same way from it. I generally think of Diffuse light as sunlight because it simulates that rather well for outdoor lighting.

It's recommended to use xLights' integreated effects to program the light bar. Good ones for getting started are: Curtain, Marble, Morph and On. Most effects can be customized using the 'Effect Settings' Window. The visualization will display all effects accurately, but keep in mind that the lights are very diffused.

I’ve never really liked the terms “ambient” and “diffuse”, but I’ve learned to live with them since they are industry standard terms. In real life, ambient light IS diffuse light. Ambient light is the light of the environment, most of which comes from reflected surfaces, which by definition is diffuse. Diffuse light is light that is not direct but has it’s path diverted from the source. Most lights would be too harsh if they were direct, so the bulb often has a coating that makes the light travel off in somewhat random directions. Often there will be some sort of translucent glass or something even after that that makes it more diffuse. The bottom line is that in real life the two terms are almost identical in meaning and the two terms really don’t do a very good job of describing the lighting in 3D graphics.

The rear light bar is grouped into the same three segments. Center consists of the 52 LEDs on the bed door, while Left/Right are 4 LEDs each above the Turn Signals.

Most lights available on the vehicle can only turn on or off instantly, which corresponds to 0% or 100% brightness of an 'Effect' in xLights.

Left inner main beam, Turn on; 2000 ms for 2.06s, Turn off; 2000 ms for 1.9s, Turn on; 2000 ms for 2.06s: causes light to ramp to 100% intensity, then down close to, but not reaching, 0% intensity, then back up to 100% intensity, then instantly turn off.

A custom show can be run on a supported vehicle by loading it via a USB flash drive. Create and share your shows with others! A single show can be shared and run on any supported vehicle; they are not model-specific. The sequence data is stored in a .fseq file and the music comes from your choice of .mp3 or .wav.

In "Map Channels" Window, select "Load Mapping" and choose "2022_mapping.xmap" located in the tesla_xlights_show_folder.

The keyboard layout is designed to be easy to use. Note that the effect types are grouped into vertical keyboard rows and sorted by duration.

Left inner main beam, Turn on; 2000 ms, effect duration 4s: causes the light to ramp from 0% to 100% intensity over 2s, then stay at 100% intensity for 2s, then instantly turn off after 4s.

So combined, the 3 give you the object’s surface color and simulate the sunlight and refracted blue sky. It works really well in simulating outdoor lighting. Make the light colors more grey for a stormy day.

All old .fseq files are fully compatible with this light show update. You only need to convert old show files if you want to edit them with the refreshed XLights configuration.

This example will cause the Aux Park lights to flash on Model 3/Y (note the blank time between each box compared to the other example):

Navigate to your chosen .wav or mp3 file, select it, then select Open. Note that .wav files may be hidden unless file type is set to xLights Audio Files.

If using the recommended "Group View", you can double click the light groups to reveal and hide individual left/right control. Placing light effects in the group object will activate both the left and right light

Now that we’ve gotten that out of the way, here’s what the terms mean in 3D graphics. Ambient light is the light I demonstrate in my “silhouette” video. It’s one color applied to everything. By itself, all it does is produce silhouettes of the objects presuming the background color is different from the ambient color. If they are the same, you won’t see anything. This type of lighting does not give you 3D any more than shadows are 3D. But it has a purpose, which is to fill in the shadow side of objects. (Note that nothing in this lighting model produces actual shadows which is another topic in and of itself.)

now we have 3 different material constants, each describes how the surface interacts with light Ka means what intensity (or color) will be reflected when ambient light shines on the surface Kd means the same for diffuse light, but is there any difference between ambient and diffuse light ? i think there isnt …

Ambient and diffuse material colours are usually identical. The main reason why they might be different is that an object in shade may have its diffuse colour darkened (but with the same hue) to provide a crude simulation of shadowing.

Value Curves can also be used to create more advanced custom brightness effects. Keep in mind that the maximum brightness is 100.

Note: any value between 15ms and 100ms is supported by the vehicle, but 20ms is recommended for nearly all use cases. The maximum show size limits do not depend on the frame interval.

This Back Side Illumination is designed for machine cameras, providing backlighting solutions. Suitable for a variety of machine vision applications.

If the files on the USB flash drive meet the requirements, then the custom shows will be available to select from the drop-down menu.

Phong reflection is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces. It is based on Phong's informal observation that shiny surfaces have small intense specular highlights, while dull surfaces have large highlights that fall off more gradually. The model also includes an ambient term to account for the small amount of light that is scattered about the...

Specular reflection is usually colourless. The most common exception is for metals such as copper or gold. Anodising or an iridescent oxide layer (a feature commonly associated with crystals of Bismuth) can also produce coloured specular reflections.

regarding specular material value: isnt reflected light almost ever completely “white” ? (Ks = vec3(1, 1, 1)) “white” means all RGB components of the intensity will be reflected completely

Ambient and diffuse light are not even remotely the same thing. If you want an in depth explanation, watch my HLSL video series. (You can probably skip the first video in the series where I talk about XNA and DirectX since you would be looking at this from an OGL perspective for GLSL. But otherwise I would go through the videos in order since they build on each other. My website has a GLSL shader that’s basically identical to the HLSL shader I have built by the end of the series. I would also be happy to repost that GLSL shader code if you wanted.)

so what speaks against using Kd again for ambient light: (Ka = Kd) vec3 Intensity = Kd * (Intensity(ambient) + Intensity(diffuse)) + Intensity(specular) * Ks;

In this example, each channel blinks 3x and ramps down after its last blink. Notice how an Turn Off, 500ms effect is added always on Channel 4, even when it's Channel 5 or Channel 6 that were turned on.
