Detailed Description

Basic 2D rendering primitives.

Function Documentation

fsClear()

void fsClear

(

FsColor

color

)

Clears the window.

Clears the window and the OpenGL context using the specified color.

Parameters

color

Clear color.

FsColor_new()

FsColor FsColor_new	(	uint8_t	r,
		uint8_t	g,
		uint8_t	b )

Creates a color.

Parameters

r	Red component (0-255).
g	Green component (0-255).
b	Blue component (0-255).

Returns

Resulting color.

fsDrawCircle()

void fsDrawCircle

(

const FsCircle *

circle

)

Draws a circle.

Draws a colored circle.

Parameters

circle

Circle to draw.

fsDrawLine()

void fsDrawLine

(

const FsLine *

line

)

Draws a line.

Draws a colored line using the provided line parameters.

Parameters

line	Line to draw.

fsDrawPixel()

void fsDrawPixel

(

const FsPoint *

p

)

Draws a pixel.

Draws a colored point at the specified position.

Parameters

p	Point to draw.

fsDrawQuad()

void fsDrawQuad

(

const FsQuad *

quad

)

Draws a quadrilateral.

Draws a colored quadrilateral.

Parameters

quad	Quadrilateral to draw.

fsDrawSprite()

void fsDrawSprite

(

const FsSprite *

sprite

)

Draws a 2D sprite.

Renders a sprite on the window using its position, size, rotation angle, and texture. The sprite is drawn as a textured quad with OpenGL.

Parameters

sprite

Pointer to the FsSprite to draw.

Note

The sprite's texture must be loaded and valid.

Uses OpenGL immediate mode for rendering.

fsDrawTriangle()

void fsDrawTriangle

(

const FsTriangle *

tri

)

Draws a triangle.

Draws a colored triangle.

Parameters

tri	Triangle to draw.

fsOrthoSet()

void fsOrthoSet	(	int	width,
		int	height )

Sets the orthographic projection.

Defines the orthographic rendering view for the current window.

Parameters

width	Width of the orthographic view.
height	Height of the orthographic view.
