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.

Modules

animation	Functions and types relating to animations.
scaling	Functions and types relating to screen scaling.
ui	Functions and types relating to user interfaces.

Structs

Camera	A camera that can be used to transform the scene.
Canvas	A texture that can be used for off-screen rendering.
Color	An RGBA color.
DrawParams	Parameters that can be manipulated when drawing an object.
Font	A font that can be used to render text.
GraphicsDeviceInfo	Information about the device currently being used to render graphics.
Rectangle	A rectangle of f32s.
Shader	A shader program, consisting of a vertex shader and a fragment shader.
Text	A piece of text that can be rendered.
Texture	A texture, held in GPU memory.

Enums

FilterMode

Filtering algorithms that can be used when scaling an image.

Constants

DEFAULT_FRAGMENT_SHADER	The default fragment shader.
DEFAULT_VERTEX_SHADER	The default vertex shader.

Traits

Drawable	Implemented for types that can be drawn.
UniformValue	Implemented for types that can be passed as a uniform value to a shader.

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_default_filter_mode	Returns the filter mode that will be used by newly created textures and canvases.
get_device_info	Retrieves information about the device currently being used to render graphics.
get_transform_matrix	Returns the current transform matrix.
present	Presents the result of drawing commands to the screen.
reset_canvas	Sets the renderer back to drawing to the screen directly.
reset_shader	Sets the renderer back to using the default shader.
reset_transform_matrix	Resets the transform matrix.
set_canvas	Sets the renderer to redirect all drawing commands to the specified canvas.
set_default_filter_mode	Sets the filter mode that will be used by newly created textures and canvases.
set_shader	Sets the shader that is currently being used for rendering.
set_texture	Sets the texture that is currently being used for rendering.
set_transform_matrix	Sets the transform matrix.
