Member Function Documentation

void AddQuad2D	(	const float	x1,
		const float	y1,
		const float	x2,
		const float	y2
	)

Add a quad defined by a 2D rectangle from x1,y1 to x2,y2

Parameters

x1	X coord of point 1
y1	Y coord of point 1
x2	X coord of point 2
y2	Y coord of point 2

void AddQuad3D

(

const Vector

v[]

)

Add a 3D quad defined by 4 3D vertices

Parameters

v	Array of 4 vertices containing the vertices of the 3D quad

void Bake

(

IGlsStateManager *

stateManager

)

Bakes the quad list, creating VBOs within the GL context. The VBOs created by Bake are used when the object is later drawn with Draw

Parameters

stateManager

The StateManager object to create the VBOs within

void Draw	(	IGlsStateManager *	stateManager,
		const bool	enableColor
	)

Draws this quad list

Parameters

stateManager	OpenGL context to draw list in
enableColor	Whether or not to use the per vertex colors when drawing

void DrawOutlines	(	IGlsStateManager *	stateManager,
		const bool	enableColor
	)

Draws this quad list as a series of line loops

Parameters

stateManager	OpenGL context to draw list in
enableColor	Whether or not to use the per vertex colors when drawing

unsigned int NumQuads ( )

inline

Returns

Returns the number of quads in the list

void SetColor

(

const glsColor &

color

)

Set the current drawing color. When a quad is added, its vertex colors are set to the current color

Parameters

color

The color to set

void SetupVBO ( IGlsStateManager *  stateManager, const bool  enableColor  )

protected

Bind the quad list's VBOs and prepare for drawing

Parameters

stateManager	OpenGL context to draw list in
enableColor	Whether or not to use the per vertex colors when drawing

void StartBuilding

(

)

Put the quad list in list building mode. Process for using this quad list:

1. Build the list
2. Bake the list (creates VBOs)
3. Draw the list

Member Data Documentation

glsColor _currentColor

protected

Last color that was set. Used only while building a list

unsigned int _indexBufferHandle

protected

Index buffer Handle for this quad storage

DynamicArray<GLushort, true> _indices

protected

Indices for the quad list

unsigned int _numQuads

protected

Number of quads in the list

unsigned int _vboBufferSize

protected

Size of the VBO buffer. Cached to so that when a quad is cleared and reset we will only reallocate the VBO when its size changes.

unsigned int _vboHandle

protected

VBO Handle for this quad storage

DynamicArray<V3f_C4ub, true> _vertData

protected

Vertices for the quad list

const void* const VERT_OFFSET

static

Constant offsets to the primitive vertex attributes.

Note

Theoretically should be GLuints, but OpenGL's functions to pass integer offsets as pointers.

const GLuint VERT_SIZE = sizeof( Vector )

static

Constant sizes of the primitive vertex attributes
