WebGL Commands Implementation

Implementations

impl WebGLImpl

pub fn apply( device: &Device, ctx: &Context, gl: &Gl, state: &mut GLState, attributes: &GLContextAttributes, command: WebGLCommand, _backtrace: WebGLCommandBacktrace, )

fn initialize_framebuffer( gl: &Gl, state: &GLState, color: bool, depth: bool, stencil: bool, )

fn link_program(gl: &Gl, program: WebGLProgramId) -> ProgramLinkInfo

fn finish(gl: &Gl, chan: &GenericSender<()>)

fn shader_precision_format( gl: &Gl, shader_type: u32, precision_type: u32, chan: &GenericSender<(i32, i32, i32)>, )

fn get_extensions(gl: &Gl, result_sender: &GenericSender<String>)

This is an implementation of getSupportedExtensions() from https://registry.khronos.org/webgl/specs/latest/1.0/#5.14

fn get_framebuffer_attachment_parameter( gl: &Gl, target: u32, attachment: u32, pname: u32, chan: &GenericSender<i32>, )

https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.6

fn read_draw_framebuffer_bits(gl: &Gl, attachment: u32, pname: u32) -> i32

Reads one component size of a draw framebuffer attachment, or 0 when nothing is attached, as OpenGL ES 3.0.6 §4.4.5 defines the *_BITS values.

fn get_renderbuffer_parameter( gl: &Gl, target: u32, pname: u32, chan: &GenericSender<i32>, )

https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.7

fn uniform_location( gl: &Gl, program_id: WebGLProgramId, name: &str, chan: &GenericSender<Option<i32>>, )

fn shader_info_log( gl: &Gl, shader_id: WebGLShaderId, chan: &GenericSender<String>, )

fn program_info_log( gl: &Gl, program_id: WebGLProgramId, chan: &GenericSender<String>, )

fn create_buffer(gl: &Gl, chan: &GenericSender<Option<WebGLBufferId>>)

fn create_framebuffer(gl: &Gl, chan: &GenericSender<Option<WebGLFramebufferId>>)

fn create_renderbuffer( gl: &Gl, chan: &GenericSender<Option<WebGLRenderbufferId>>, )

fn create_texture(gl: &Gl, chan: &GenericSender<Option<WebGLTextureId>>)

fn create_program(gl: &Gl, chan: &GenericSender<Option<WebGLProgramId>>)

fn create_shader( gl: &Gl, shader_type: u32, chan: &GenericSender<Option<WebGLShaderId>>, )

fn create_vertex_array(gl: &Gl) -> Option<WebGLVertexArrayId>

fn bind_framebuffer( gl: &Gl, target: u32, request: WebGLFramebufferBindingRequest, ctx: &Context, device: &Device, state: &mut GLState, )

fn default_framebuffer_color_buffer( buffer: u32, ctx: &Context, device: &Device, ) -> u32

Maps a WebGL default framebuffer color buffer to its GL name: when the surface is backed by a framebuffer object, GL rejects BACK and uses COLOR_ATTACHMENT0 for the color buffer.

fn compile_shader(gl: &Gl, shader_id: WebGLShaderId, source: &str)
