Detailed Description

Shader parameter node storing a buffer object.

This node allows the application to provide a buffer object to a shader program. The shader program can access this buffer as a GLSL Shader Storage Buffer Object.

SoShaderParameterBufferObject nodes are usually added to the shader program's bufferObjects field to affect only that specific shader program, but can also be inserted in the scene graph and affect all subsequent shader programs.

NOTE: If inserted directly in the scene graph, SoShaderParameterBufferObject is not cacheable. This means that all parent SoSeparator nodes will not be able to create render caches. This may reduce rendering performance.

FILE FORMAT/DEFAULT

SoShaderParameterBufferObject {

bindingPoint	0
buffer	NULL
bufferType	SHADER_STORAGE_BUFFER

}

NOTE: node available since Open Inventor 9.8

Member Data Documentation

SoSFInt32 SoShaderParameterBufferObject::bindingPoint

An integer matching the 'binding' value specified in the GLSL shader code.

Default is 0.

SoSFBufferObject SoShaderParameterBufferObject::buffer

An SoBufferObject containing data.

In order to avoid a CPU to GPU copy, it is recommended to use an SoGLBufferObject. Default is null.

SoSFEnum SoShaderParameterBufferObject::bufferType

The buffer type.

Default is SHADER_STORAGE_BUFFER. The only legal value is SHADER_STORAGE_BUFFER for now.
