Rezmason	23d397fa11	Now that I can pack integer and float data into one uniform buffer, time.seconds can be represented as a float while time.frames is an integer.	2021-10-29 09:02:20 -07:00
Rezmason	d4b21a0e4c	Moving std140 code to its own module. Here it can evolve into a class or whatever, and it won't clutter the rest of the code.	2021-10-29 08:03:55 -07:00
Rezmason	e79e741fcf	Fixed a struct layout bug. Struct layout and builder now support mixing integer and float data in a struct, and output an ArrayBuffer.	2021-10-29 07:43:39 -07:00
Rezmason	81f77c70ae	Slowly working out what's required to support uniform buffers that store integers as well as floats	2021-10-29 00:38:58 -07:00
Rezmason	ad2b7e53af	buildStruct needs to convert values into arrays	2021-10-28 23:56:31 -07:00
Rezmason	1b53b8be1f	Experimenting with simplifying the names of the uniform buffers in the rain render pass shader.	2021-10-28 22:21:01 -07:00
Rezmason	c500bdcef0	Implemented rudimentary support for std140 alignment of values in uniform buffers.	2021-10-28 21:22:13 -07:00
Rezmason	a3c99ff4c0	Swapping the camera perspective generating function to mat4.perspectiveZO.	2021-10-27 22:45:29 -07:00
Rezmason	c3254c3aa1	Adding WebGPU to TODO.md. Annotating the parts of the WebGPU code that involve uniform buffer layout issues.	2021-10-27 22:34:47 -07:00
Rezmason	c27c20f2cf	Consolidating all the bind groups, because I only have four. Stuff shared between render passes will get isolated somehow, but it might be by binding one buffer to multiple render passes' bind group at zero rather than having more than one bind group.	2021-10-27 21:08:20 -07:00
Rezmason	a0649bdb34	Added screenSize in camera uniforms.	2021-10-27 20:51:22 -07:00
Rezmason	f2a54b3141	A little bit of shader variable renaming and const declaration during a walkthrough of the existing code on-stream	2021-10-27 20:00:39 -07:00
Rezmason	c716d30808	Merged the vertex and fragment shader WGSL files, because their bindings can't collide anyhow. The rain render shader now accepts a bind group of time uniforms, which change on every frame, as well as MSDF uniforms, along with an MSDF sampler and texture that's loaded in from the PNG. The shader currently renders the correct grid of quads for volumetric mode, displays the first glyph raw in each one, and every sixty frames, turns on and off the blue channel.	2021-10-27 19:04:02 -07:00
Rezmason	8c62146884	Fetching WebGPU shaders. Created my first bona fide pipeline. The vertex shader compares the built-in vertex index and the numRows/numColumns uniforms to produce a grid of quads with no vertex or index buffer whatsoever!	2021-10-27 19:04:02 -07:00
Rezmason	1827fd94a6	Removing document onload function from webgpu_main that I left in by mistake	2021-10-27 19:04:02 -07:00
Rezmason	3cb20139c4	Creating stump render bundle array. This is how WebGPU command buffers are created and executed.	2021-10-27 19:04:02 -07:00
Rezmason	6b317af0bb	Broke ground on webgpu version. ... Split regl_main.js off of main.js, which now detects navigator.gpu. If it exists, it initializes webgpu_main instead.	2021-10-27 19:04:02 -07:00
