glCreateShader — Creates a shader object
GLuint glCreateShader(
|
GLenum shaderType) ; |
shaderType
Specifies the type of shader to be created.
GL_VERTEX_SHADER
,
GL_FRAGMENT_SHADER
, or
GL_COMPUTE_SHADER
,
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. Three types of
shaders are supported. 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_FRAGMENT_SHADER
is a shader that
is intended to run on the programmable fragment processor. A
shader of type GL_COMPUTE_SHADER
is a
shader that is intended to run on the programmable compute
processor.
When created, a shader object's
GL_SHADER_TYPE
parameter is set to
GL_COMPUTE_SHADER
,
GL_VERTEX_SHADER
or
GL_FRAGMENT_SHADER
, depending on the value
of shaderType
.
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 3.1 or higher.
This function returns 0 if an error occurs creating the shader object.
GL_INVALID_ENUM
is generated if
shaderType
is not an accepted
value.
glGetShaderiv with a valid shader object and the parameter to be queried
glGetShaderInfoLog with a valid shader object
