NAME¶
glCreateShader - Creates a shader object
C SPECIFICATION¶
GLuint
glCreateShader(GLenum shaderType);
PARAMETERS¶
shaderType
Specifies the type of shader to be created. Must be one
of GL_COMPUTE_SHADER, GL_VERTEX_SHADER,
GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER,
GL_GEOMETRY_SHADER, or GL_FRAGMENT_SHADER.
DESCRIPTION¶
glCreateShader creates an empty shader object and returns a non-zero
value by which it can be referenced. A shader object is used to maintain the
source code strings that define a shader.
shaderType indicates the type
of shader to be created. Five types of shader are supported. A shader of type
GL_COMPUTE_SHADER is a shader that is intended to run on the
programmable compute processor. A shader of type
GL_VERTEX_SHADER is a
shader that is intended to run on the programmable vertex processor. A shader
of type
GL_TESS_CONTROL_SHADER is a shader that is intended to run on
the programmable tessellation processor in the control stage. A shader of type
GL_TESS_EVALUATION_SHADER is a shader that is intended to run on the
programmable tessellation processor in the evaluation stage. A shader of type
GL_GEOMETRY_SHADER is a shader that is intended to run on the
programmable geometry processor. A shader of type
GL_FRAGMENT_SHADER is
a shader that is intended to run on the programmable fragment processor.
When created, a shader object's
GL_SHADER_TYPE parameter is set to either
GL_COMPUTE_SHADER,
GL_VERTEX_SHADER,
GL_TESS_CONTROL_SHADER,
GL_TESS_EVALUATION_SHADER,
GL_GEOMETRY_SHADER or
GL_FRAGMENT_SHADER, depending on the value
of
shaderType.
NOTES¶
Like buffer and texture objects, the name space for shader objects may be shared
across a set of contexts, as long as the server sides of the contexts share
the same address space. If the name space is shared across contexts, any
attached objects and the data associated with those attached objects are
shared as well.
Applications are responsible for providing the synchronization across API calls
when objects are accessed from different execution threads.
GL_COMPUTE_SHADER is available only if the GL version is 4.3 or higher.
ERRORS¶
This function returns 0 if an error occurs creating the shader object.
GL_INVALID_ENUM is generated if
shaderType is not an accepted
value.
