WebAug 3, 2024 · 1. I recently re-wrote some code to use Shader Storage Buffer Object in OpenGL, to send in dynamic sized arrays into GLSL, vastly increasing performance when drawing many procedurally generated objects. What I have is a couple of thousand points, and for each point I render a procedurally generated circular billboard.

Path tracing cosine hemisphere sampling and emissive objects
WebPath tracing is a method of rendering images faithful to reality. The core algorithm of this WebGL Path Tracer is implemented in GLSL fragment shader. Each ray bounces in the scene around five times. A Demo is uploaded in YouTube and code is provided in GitHub. Features: Diffuse and Blinn-Phong; Fresnel Reflection and Refraction; Subsurface ... WebFeb 15, 2024 · @bobobobo: "So technically you could set a uniform vec4 using glUniform1fv( uniformId, 4, v ) ; where v is an array of 4 floats." No, you can't. The spec is very clear: the size and type must match the uniform's size and type (except for bools which use i and opaques which use 1i).If you say 1f, then the uniform must be 1 … teachers avenue
