Module tetra::graphics

Functions and types relating to rendering.

This module implements a (hopefully!) efficent quad renderer, which will queue up drawing operations until it is absolutely necessary to send them to the graphics hardware. This allows us to minimize the number of draw calls made, speeding up rendering.

Functions

clear	Clears the screen (or a canvas, if one is enabled) to the specified color.
draw	Draws an object to the screen (or to a canvas, if one is enabled).
flush	Sends queued data to the graphics hardware.
get_internal_height	Gets the internal height of the screen.
get_internal_size	Gets the internal size of the screen.
get_internal_width	Gets the internal width of the screen.
get_scaling	Gets the current scaling mode.
present	Presents the result of drawing commands to the screen, scaling/letterboxing if necessary.
reset_canvas	Sets the renderer back to drawing to the screen directly.
reset_shader	Sets the renderer back to using the default shader.
set_canvas	Sets the renderer to redirect all drawing commands to the specified canvas.
set_internal_height	Sets the internal height of the screen.
set_internal_size	Sets the internal size of the screen.
set_internal_width	Sets the internal width of the screen.
set_letterbox_color	Sets the color of the letterbox bars that are displayed when scaling the screen.
set_scaling	Sets the current scaling mode.
set_shader	Sets the shader that is currently being used for rendering.
set_texture	Sets the texture that is currently being used for rendering.

Type Definitions

Vec2	A 2D vector with f32 components.
