RemarksThis node defines a compute shader, a shader stage used entirely for computing arbitrary information.
To store the result of the computation, an OIV.Inventor.Nodes.SoComputeShader may use OIV.Inventor.Nodes.SoShaderParameterImage or OIV.Inventor.Nodes.SoShaderParameterBufferObject with OIV.Inventor.Nodes.SoShaderParameterBufferObject.BufferTypes.SHADER_STORAGE_BUFFER buffer type.
To fetch data, an OIV.Inventor.Nodes.SoComputeShader may use the above-mentioned parameter types, or regular texture access.
See OIV.Inventor.Nodes.SoShaderProgram for general information about using shaders and shader parameters.
See parent class OIV.Inventor.Nodes.SoShaderObject for details about using the inherited fields.
See OIV.Inventor.Nodes.SoComputeShaderScheduler for information about compute shader invocation.
Notes & Limitations:
Compute shaders cannot coexist with other shader stages in the same shader program. Otherwise, an error will be generated and the shader won't compile (for example, you cannot insert an OIV.Inventor.Nodes.SoFragmentShader along with an OIV.Inventor.Nodes.SoComputeShader into the field OIV.Inventor.Nodes.SoShaderProgram.shaderObject).
An OIV.Inventor.Nodes.SoShaderProgram containing compute shaders cannot be applied on OIV.Inventor.Nodes.SoShape nodes. If such a shader program is present on state when a shape is traversed by a rendering action, errors might be raised and the shape will not be rendered. To avoid this case, those OIV.Inventor.Nodes.SoShaderProgram should be isolated in their own OIV.Inventor.Nodes.SoSeparator, along with the OIV.Inventor.Nodes.SoComputeShaderScheduler nodes.
