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.

Member Data Documentation

◆ buffer

SoSFBufferObject SoShaderParameterBufferObject::buffer

An SoBufferObject containing data.

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

Definition at line 86 of file SoShaderParameterBufferObject.h.

◆ bufferType

SoSFEnum SoShaderParameterBufferObject::bufferType

The buffer type.

Default is SHADER_STORAGE_BUFFER. The only legal values are SHADER_STORAGE_BUFFER and UNIFORM_BUFFER.
