Documentation

Overview

Package renderers implement the drawing code for specific rendering APIs. The renderers in here are dependent on the context the platform provides and process the drawing commands from imgui by driving the rendering API.

Types

type OpenGL2

type OpenGL2 struct {
	// contains filtered or unexported fields
}

OpenGL2 implements a renderer based on github.com/go-gl/gl (v2.1).

func NewOpenGL2

func NewOpenGL2(io imgui.IO) (*OpenGL2, error)

NewOpenGL2 attempts to initialize a renderer. An OpenGL context has to be established before calling this function.

func (*OpenGL2) Dispose

func (renderer *OpenGL2) Dispose()

Dispose cleans up the resources.

func (*OpenGL2) PreRender

func (renderer *OpenGL2) PreRender(clearColor [3]float32)

PreRender clears the framebuffer.

func (*OpenGL2) Render

func (renderer *OpenGL2) Render(displaySize [2]float32, framebufferSize [2]float32, drawData imgui.DrawData)

Render translates the ImGui draw data to OpenGL3 commands.

type OpenGL3

type OpenGL3 struct {
	// contains filtered or unexported fields
}

OpenGL3 implements a renderer based on github.com/go-gl/gl (v3.2-core).

func NewOpenGL3

func NewOpenGL3(io imgui.IO) (*OpenGL3, error)

NewOpenGL3 attempts to initialize a renderer. An OpenGL context has to be established before calling this function.

func (*OpenGL3) Dispose

func (renderer *OpenGL3) Dispose()

Dispose cleans up the resources.

func (*OpenGL3) PreRender

func (renderer *OpenGL3) PreRender(clearColor [3]float32)

PreRender clears the framebuffer.

func (*OpenGL3) Render

func (renderer *OpenGL3) Render(displaySize [2]float32, framebufferSize [2]float32, drawData imgui.DrawData)

Render translates the ImGui draw data to OpenGL3 commands.
