RenderFactory class

RenderFactory creates all resources that represented in rendering pipeline.

The RenderFactory type exposes the following members:

Method	Description
`create_render_texture(self, parameters, targets, width, height)`	Create a render target that renders to the texture
`create_render_texture(self, parameters, width, height)`	Create a render target contains 1 targets that renders to the texture
`create_texture_unit(self, texture_type)`	Create a texture unit that can be accessed by shader.
`create_texture_unit(self)`	Create a 2D texture unit that can be accessed by shader.
`create_descriptor_set(self, shader)`	Create the descriptor set for specified shader program.
`create_cube_render_texture(self, parameters, width, height)`	Create a render target contains 1 cube texture
`create_render_window(self, parameters, handle)`	Create a render target that renders to the native window.
`create_vertex_buffer(self, declaration)`	Create an `IVertexBuffer` instance to store polygon’s vertex information.
`create_index_buffer(self)`	Create an `IIndexBuffer` instance to store polygon’s face information.
`create_shader_program(self, shader_source)`	Create a `ShaderProgram` object
`create_pipeline(self, shader, render_state, vertex_declaration, draw_operation)`	Create a preconfigured graphics pipeline with preconfigured shader/render state/vertex declaration and draw operations.
`create_uniform_buffer(self, size)`	Create a new uniform buffer in GPU side with pre-allocated size.
