Types

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.ImGuiIO) (*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.ImDrawData)

Render translates the ImGui draw data to OpenGL3 commands.
