Static compileShader

compileShader(gl: WebGLRenderingContext, type: number, source: string): WebGLShader

- Defined in src/utils/GLProgram.ts:133
Compiles source into a program.

Parameters
- gl: WebGLRenderingContext
  
  The rendering context.
- type: number
  
  The type, can be either gl.VERTEX_SHADER or gl.FRAGMENT_SHADER.
- source: string
  
  The fragment shader source as an array of strings.
Returns WebGLShader
