Detailed Description

Basic graphics module for simple graphics drawing or prototyping purposes.

Because these graphics functions send vertex data directly to the GX, it is best not to call these routines too redundantly otherwise, a slowdown will occur.

These functions are mostly meant for prototyping purposes.

Function Documentation

DrawBox()

void gdl::DrawBox	(	short	x1,
		short	y1,

[in]	x2	X coordinate of lower-right point of box.
[in]	y2	Y coordinate of lower-right point of box.
[in]	col	Color of point (see gdl::Color::ColorValues or Color Handling Macros).

DrawBoxF()

void gdl::DrawBoxF	(	short	x1,
		short	y1,
		short	x2,
		short	y2,
		u_int	col
	)

Draws a filled box.

Parameters

[in]	x2	X coordinate of lower-right point of box.
[in]	y2	Y coordinate of lower-right point of box.
[in]	col	Color of point (see gdl::Color::ColorValues or Color Handling Macros).

DrawBoxFG()

void gdl::DrawBoxFG	(	short	x1,
		short	y1,
		short	x2,
		short	y2,
		u_int	tl_col,
		u_int	tr_col,
		u_int	br_col,
		u_int	bl_col
	)

Draws a filled gouraud-shaded box.

Parameters

[in]	x1	X coordinate of upper-left point of box.
[in]	y1	Y coordinate of upper-left point of box.
[in]	x2	X coordinate of lower-right point of box.
[in]	y2	Y coordinate of lower-right point of box.

[in]	br_col	Color of bottom-right point of box.
[in]	bl_col	Color of bottom-left point of box.

DrawBoxG()

void gdl::DrawBoxG	(	short	x1,
		short	y1,
		short	x2,
		short	y2,
		u_int	tl_col,
		u_int	tr_col,
		u_int	br_col,
		u_int	bl_col
	)

Draws a gouraud-shaded box.

Parameters

[in]	x1	X coordinate of upper-left point of box.
[in]	y1	Y coordinate of upper-left point of box.
[in]	x2	X coordinate of lower-right point of box.
[in]	y2	Y coordinate of lower-right point of box.
[in]	tl_col	Color of top-left point of box (see gdl::Color::ColorValues or Color Handling Macros).
[in]	tr_col	Color of top-right point of box.
[in]	br_col	Color of bottom-right point of box.
[in]	bl_col	Color of bottom-left point of box.

DrawLine()

void gdl::DrawLine	(	short	x1,
		short	y1,
		short	x2,
		short	y2,
		u_int	col
	)

Draws a line.

You can adjust the point size with GX_SetLineWidth() but its going to be tricky since the function doesn't really take sizes in pixels exactly.

Parameters

[in]	x1	X coordinate of start point of line.
[in]	y1	Y coordinate of start point of line.
[in]	x2	X coordinate of end point of line.
[in]	y2	Y coordinate of end point of line.
[in]	col	Color of point (see gdl::Color::ColorValues or Color Handling Macros).

DrawLineG()

void gdl::DrawLineG	(	short	x1,
		short	y1,
		short	x2,
		short	y2,
		u_int	col_a,
		u_int	col_b
	)

Draws a gouraud-shaded line.

Parameters

[in]	x1	X coordinate of start point of line.
[in]	y1	Y coordinate of start point of line.
[in]	x2	X coordinate of end point of line.
[in]	y2	Y coordinate of end point of line.
[in]	col_a	Color of start point of line (see gdl::Color::ColorValues or Color Handling Macros).
[in]	col_b	Color of end point of line.

DrawPoint()

void gdl::DrawPoint	(	short	x,
		short	y,
		u_int	col
	)

Draws a point or a single pixel.

You can adjust the point size with GX_SetPointSize() but its going to be tricky since the function does not exactly take the size in pixels units.

Parameters

[in]	x	X coordinate of point.
[in]	y	Y coordinate of point.
[in]	col	Color of point (see gdl::Color::ColorValues or Color Handling Macros).
