`MVTLayer` requires documention

4

It requires template parameters, but it's unclear what should be used. I ended up using `as any` on the props, too. I think there should be more samples and documentation...

[This simple bit of code from the deck.gl docs won't work](https://deck.gl/docs/developer-guide/custom-layers/primitive-layers#creating-the-model) when copied naively: - "Error: TS2707: Generic type 'Layer' requires between 1 and 2 type arguments." leads to: -...

Add option to reset min and max in bookmarklet

2

I believe that starting the stats bookmarklet can introduce a spike in the green ms/Frame display, so the "max" often jumps to 30 or higher, even if the framerate is...

As pointed out here https://github.com/toji/gl-matrix/issues/279#issuecomment-375895923, `vec4.transformMat4` doesn't do w-division, and the user is responsible for doing it: https://github.com/toji/gl-matrix/blob/21b745f3a8b095c4a5304978fa8ab131b76a5f9e/src/vec4.js#L478-L488 For `vec3.transformMat4` (assumes `w=1`), the W-division is done, presumably because the `w`-component...

[Bug] Division by zero in `TripsLayer` if 2 consecutive coordinates share the same location

### Description Originally reported on Slack, but I'm moving it here for exposure: The bug is in: https://github.com/visgl/deck.gl/blob/e32b546539b859933be006069f3301a8e4323b1e/modules/geo-layers/src/trips-layer/trips-layer.js#L42 When 2 consecutive coordinates share the same coordinate, they’ll have `vPathLength` of...

This [issue originated from a Slack discussion](https://deckgl.slack.com/archives/C34AC5MSQ/p1627552946367700?thread_ts=1627377292.275600&cid=C34AC5MSQ) I originally wanted to create a PR, but while trying to fix it, I was unsure how to implement my hack properly. ####...

GLSL ES 1.00 compatibility

1

I'm unable to find which versions of GLSL are supported. I'd like to write code for WebGL 1 (~ OpenGL ES 2.0) in GLSL ES 1.00. I'm trying to do...

**bug.glsl** ```glsl #version 100 #define SAMPLER_COUNT 2 uniform sampler2D samplers[SAMPLER_COUNT]; void main() { vec4 sum = vec4(0.0); for(int i = 0; i < SAMPLER_COUNT; i++) { sum += samplers[i]; }...

Map repaint is slow / CPU and GPU intensive

*(This is a meta-issue, I hope we can create more performance related issues and documentation over time)* As graphics programmer, I have the task of adding animations to our maps...

Strategy for tile-prefetching during camera-movement

34

We often use `flyTo`, but maplibre doesn't seem to be smart enough to prefetch tiles along the animation path. The same is true for user mouse-movement (pan / zoom /...
