Constructor & Destructor Documentation

Renderer()

oe::gui::Renderer::Renderer ( )

explicit

Constructor. Prepare the renderer.

Parameters

manager

GUI manager

Member Function Documentation

setFontBlankData()

void oe::gui::Renderer::setFontBlankData	(	const render::Texture *	texture,
		const glm::vec2 &	uv
	)

Set uv coordinates and texture containing an opaque white pixel.

Used to draw anything that is not a text

Note

It is suggested to have the white pixel somewhere inside your main "font" texture

Parameters

texture	Texture containing a white pixel
uv	Texture coordinates of the white pixel

Member Data Documentation

shader

std::unique_ptr<oe::render::Shader> oe::gui::Renderer::shader

Shader used for rendering the GUI.

We send the some inputs to the shader To be compatible, your shaders must (at least) use those same inputs

Vertex layout:

// Vertex position
layout (location = 0) in vec2 aPosition;
 
// Texture coordinates
layout (location = 1) in vec2 aTexCoords;
 
// Color to multiply to texture
layout (location = 2) in vec4 aColor;

Uniforms:

// Projection matrix to draw the UI
uniform mat4 uProjection;
 
// UI component specific texture (can be font glyphs or image)
uniform sampler2D uTexture;
