project

A basic projection module.

Makes it easy to ensure a set of shaders all use the same uniforms when calculating positions.

Parameters​

getUniforms take the following parameters when the picking module is included.

  • projection (Array[16], false) -
  • view (Array[16], identity) -

Vertex Shader Functions​

vec4 project_toClipspace(vec4 point)​

The most frequently used project operation.

  • point (vec3) - Projects a point to clipspace

Example:

// A "minimal" vertex shader
void main(void) {
  gl_Position = project_toClipspace(position);
}

Fragment Shader Functions​

The same functions that are available to the vertex shader are also available to the fragment shader. This is intended to support e.g. lighting calculations in the fragment shader.
