		float *	rgba
	)		const

virtual

Reimplemented from Graphics::Font.

Definition at line 153 of file texturefont.cpp.

References _chars, _mesh, _spaceR, and Graphics::Mesh::MeshFont::render().

Here is the call graph for this function:

◆ renderBind()

void Graphics::Aurora::TextureFont::renderBind ( const glm::mat4 & transform ) const

virtual

Bind the font for rendering.

Must be performed before render is called.

Parameters

transform Base modelview transform. Under most circumstances this is expected to be the identity matrix.

Mesh data will be dynamically updated for each character drawn to the screen (at least for now), so make sure the mesh VBO is bound. This isn't required for GL2.1, but is for GL3.2 because using the VAO doesn't automatically bind the VBO for data updates.
