- exception ShaderException
- class Attribute(name, location, count, gl_type, normalize)
Abstract accessor for an attribute in a mapped buffer.
- enable()
Enable the attribute.
- get_region(buffer, start, count)
Map a buffer region using this attribute as an accessor.
The returned region consists of a contiguous array of component data elements. For example, if this attribute uses 3 floats per vertex, and the count parameter is 4, the number of floats mapped will be
3 * 4 = 12.- Parameters
- bufferAbstractMappable
The buffer to map.
- startint
Offset of the first vertex to map.
- countint
Number of vertices to map
- Return type
AbstractBufferRegion
- set_pointer(ptr)
Setup this attribute to point to the currently bound buffer at the given offset.
offsetshould be based on the currently bound buffer’sptrmember.- Parameters
- offsetint
Pointer offset to the currently bound buffer for this attribute.
- set_region(buffer, start, count, data)
Set the data over a region of the buffer.
- Parameters
- bufferAbstractMappable`
The buffer to modify.
- startint
Offset of the first vertex to set.
- countint
Number of vertices to set.
data : A sequence of data components.
- class ComputeShaderProgram(source: str)
OpenGL Compute Shader Program
- static dispatch(x: int = 1, y: int = 1, z: int = 1, barrier: int = 4294967295) None
Launch one or more compute work groups.
The ComputeShaderProgram should be active (bound) before calling this method. The x, y, and z parameters specify the number of local work groups that will be dispatched in the X, Y and Z dimensions.
- static stop()
- static unbind()
- limits
- class Shader(source_string: str, shader_type: str)
OpenGL shader.
Shader objects are compiled on instantiation. You can reuse a Shader object in multiple ShaderPrograms.
shader_type is one of
'compute','fragment','geometry','tesscontrol','tessevaluation', or'vertex'.- property id
- class ShaderProgram(*shaders: Shader)
OpenGL shader program.
- bind()
- static stop()
- static unbind()
- use()
- vertex_list(count, mode, batch=None, group=None, **data)
Create a VertexList.
- Parameters
- countint
The number of vertices in the list.
- modeint
OpenGL drawing mode enumeration; for example, one of
GL_POINTS,GL_LINES,GL_TRIANGLES, etc. This determines how the list is drawn in the given batch.- batch~pyglet.graphics.Batch
Batch to add the VertexList to, or
Noneif a Batch will not be used. Using a Batch is strongly recommended.- group~pyglet.graphics.Group
Group to add the VertexList to, or
Noneif no group is required.- **datastr or tuple
Attribute formats and initial data for the vertex list.
- Return type
- vertex_list_indexed(count, mode, indices, batch=None, group=None, **data)
Create a IndexedVertexList.
- Parameters
- countint
The number of vertices in the list.
- modeint
OpenGL drawing mode enumeration; for example, one of
GL_POINTS,GL_LINES,GL_TRIANGLES, etc. This determines how the list is drawn in the given batch.- indicessequence of int
Sequence of integers giving indices into the vertex list.
- batch~pyglet.graphics.Batch
Batch to add the VertexList to, or
Noneif a Batch will not be used. Using a Batch is strongly recommended.- group~pyglet.graphics.Group
Group to add the VertexList to, or
Noneif no group is required.- **datastr or tuple
Attribute formats and initial data for the vertex list.

- property id
- property uniform_blocks
- property uniforms
- class ShaderSource(source: str, source_type: c_uint)
GLSL source container for making source parsing simpler.
We support locating out attributes and applying #defines values.
NOTE: We do assume the source is neat enough to be parsed this way and don’t contain several statements in one line.
- class UniformBlock(program, name, index, size, uniforms)
- create_ubo(index=0)
Create a new UniformBufferObject from this uniform block.
- Parameters
- indexint
The uniform buffer index the returned UBO will bind itself to. By default, this is 0.
- Return type
- index
- name
- program
- size
- uniforms
- view_cls
