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.
text	Functions and types relating to text rendering.
ui	Functions and types relating to user interfaces.

Structs

BorderRadii	The radius of each corner of a rounded rectangle.
Camera	A camera that can be used to transform the player's view of 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.
GeometryBuilder	A builder for creating primitive shape geometry, and associated buffers/meshes.
GraphicsDeviceInfo	Information about the device currently being used to render graphics.
IndexBuffer	Index data, stored in GPU memory.
Mesh	A 2D mesh that can be drawn to the screen.
Rectangle	A rectangle, represented by a top-left position, a width and a height.
Shader	A shader program, consisting of a vertex shader and a fragment shader.
Texture	A texture, held in GPU memory.
Vertex	An individual piece of vertex data.
VertexBuffer	Vertex data, stored in GPU memory.

Enums

BufferUsage	The expected usage of a GPU buffer.
FilterMode	Filtering algorithms that can be used when scaling an image.
ShapeStyle	Ways of drawing a shape.
VertexWinding	The ordering of the vertices in a piece of geometry.

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_front_face_winding	Returns whether clockwise or counter-clockwise ordered vertices are currently considered front-facing.
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_front_face_winding	Sets whether clockwise or counter-clockwise ordered vertices should be considered front-facing.
set_shader	Sets the shader that is currently being used for rendering.
set_transform_matrix	Sets the transform matrix.
