Namespace: rlGL

Methods

(static) buildProgram(GL, shaders) → {WebGLProgram|null}

Creates, attaches given shaders, links, validates and returns a WebGLProgram object using the given context.
(writes link/validation errors to the console)

Parameters:

Name	Type	Description
GL	WebGLRenderingContext	the rendering context to use
shaders	Array.<WebGLShader>	the array of previously build WebGLShader objects to attach to the created program

Returns:

a program object or null on a link/validation error

Type

WebGLProgram | null

(static) buildShader(GL, shaderType, shaderSource) → {WebGLShader|null}

Creates, compiles and returns a WebGLShader object using the given context.
(writes compilation errors to the console)

Parameters:

Name	Type	Description
GL	WebGLRenderingContext	the rendering context to use
shaderType	GLenum	pass GL.VERTEX_SHADER or GL.FRAGMENT_SHADER
shaderSource	String	the sourcecode for the shader in "OpenGL ES Shading Language" (the String must be in UTF-16 format)

Returns:

a shader object or null on a compilation error

Type

WebGLShader | null

(static) loadProgram(GL, shaderDescriptions, onLoadProgramFinished)

Asynchronously loads shader source files and afterwards compiles/links them as a new WebGLProgram object using the given context.
After success/failure it calls the function passed as the onLoadProgramFinished parameter.
(it is not safe to call this again before the callback started)
(writes any errors(loading/compiling/linking/validating) to the console)

Parameters:

Name	Type	Description
GL	WebGLRenderingContext	the rendering context to use
shaderDescriptions	Array.<String>	each string expected as "type:sourceURL" where type is V for FRAGMENT_SHADER or F for VERTEX_SHADER and sourceURL is the URL for the file containing the shader source code in "OpenGL ES Shading Language"
onLoadProgramFinished	rlGL~onLoadProgramFinished	a function to call after success or failure

Type Definitions

onLoadProgramFinished(glp)

Function signature for parameter onLoadProgramFinished.

Parameters:

Name	Type	Description
glp	WebGLProgram | null	a WebGLProgram object on success, null if any error occured
