Deprecated. Use API v2 vrdGLSLShaderChunk and vrdGLSLShaderParameter types instead.

The SHLChunkPtr class provides direct access to all data of an OpenGL Shader Chunk.

Method Details

__init__(source)
(Constructor)

 

The constructor of the vrSHLChunkPtr class. There are four valid versions:

vrSHLChunkPtr() Creates a vrTextureChunkPtr object.

vrSHLChunkPtr(source) Creates a vrTextureChunkPtr object from an unsigned int.

vrSHLChunkPtr(source) Creates a vrTextureChunkPtr object from a StateChunkPtr.

vrSHLChunkPtr(source) Creates a vrTextureChunkPtr object from a SHLChunkPtr.

Parameters:
  • source (unsigned int or StateChunkPtr or SHLChunkPtr) - The source (Optional).
Overrides: SHLChunkPtr.__init__

fields()

 

Returns the field access.

Returns:
The field access.

getID()

 

Returns the node id.

Returns: unsigned integer
The node id.

getPtr()

 

Returns the OpenSG SHLChunkPtr.

Returns: SHLChunkPtr
The node pointer.

isValid()

 

Returns true when the node is valid. Should be called for sanity reasons after searching a material with findMaterial.

Returns: bool
True if the node is valid, false otherwise.

setUniformParameterInt(name, v)

 

Sets an OpenGL Shading Language integer parameter.

Parameters:
  • name (string) - The name of the parameter.
  • v (integer) - The value.

setUniformParameterReal(name, v)

 

Sets an OpenGL Shading Language real parameter.

Parameters:
  • name (string) - The name of the parameter.
  • v (float) - The value.

setUniformParameterVec2f(name, x, y)

 

Sets an OpenGL Shading Language vec2f parameter.

Parameters:
  • name (string) - The name of the parameter.
  • x (float) - The x value.
  • y (float) - The y value.

setUniformParameterVec3f(name, x, y, z)

 

Sets an OpenGL Shading Language vec3f parameter.

Parameters:
  • name (string) - The name of the parameter.
  • x (float) - The x value.
  • y (float) - The y value.
  • z (float) - The z value.

setUniformParameterVec4f(name, x, y, z, w)

 

Sets an OpenGL Shading Language vec4f parameter.

Parameters:
  • name (string) - The name of the parameter.
  • x (float) - The x value.
  • y (float) - The y value.
  • z (float) - The z value.
  • w (float) - The w value.
