WebGPU API

The webcc::wgpu module provides an interface to the WebGPU API.

Note: This API is experimental and subject to change.

Header

#include "webcc/wgpu.h"

Initialization

WebGPU initialization is asynchronous.

void request_adapter();
void request_device(webcc::WGPUAdapter adapter);

You must listen for AdapterReadyEvent and DeviceReadyEvent to proceed.

Functions

Device & Queue

webcc::WGPUQueue get_queue(webcc::WGPUDevice device);
void configure(webcc::WGPUContext context, webcc::WGPUDevice device, webcc::string_view format);

Shaders & Pipelines

webcc::WGPUShaderModule create_shader_module(webcc::WGPUDevice device, webcc::string_view code);
webcc::WGPURenderPipeline create_render_pipeline_simple(webcc::WGPUDevice device, webcc::WGPUShaderModule vs_module, webcc::WGPUShaderModule fs_module, webcc::string_view vs_entry, webcc::string_view fs_entry, webcc::string_view format);

Command Encoding

webcc::WGPUCommandEncoder create_command_encoder(webcc::WGPUDevice device);
webcc::WGPUCommandBuffer finish_encoder(webcc::WGPUCommandEncoder encoder);
void queue_submit(webcc::WGPUQueue queue, webcc::WGPUCommandBuffer command_buffer);

Render Pass

webcc::WGPUTextureView get_current_texture_view(webcc::WGPUContext context);
webcc::WGPURenderPass begin_render_pass(webcc::WGPUCommandEncoder encoder, webcc::WGPUTextureView view, float r, float g, float b, float a);
void end_pass(webcc::WGPURenderPass pass);

Drawing

void set_pipeline(webcc::WGPURenderPass pass, webcc::WGPURenderPipeline pipeline);
void draw(webcc::WGPURenderPass pass, int32_t vertex_count, int32_t instance_count, int32_t first_vertex, int32_t first_instance);
