Function Documentation

void NvDrawCube

(

GLuint

posIndex

)

Draw a cube with positions.

Renders a normalized cube ([-1.0, 1.0] in X, Y, and Z) using the currently-bound shader Binds the vertex position array to the given attribute array index and draws the object using the bound shader

Parameters:

[in]

posIndex

the vertex attribute array index that represents position in the current shader

void NvDrawPoint	(	nv::vec3f &	pos,
		GLuint	posIndex
	)

Draw a single point with given position.

Renders a single point (GL_POINTS) using the currently-bound shader Binds the vertex position array to the given attribute array index and draws one point using the bound shader

Parameters:

[in]	pos	the point to be drawn
[in]	posIndex	the vertex attribute array index that represents position in the current shader

void NvDrawQuad	(	GLint	positionAttrib,
		GLint	texcoordAttrib
	)

Draw a 2D quad with positions and UVs.

Renders a normalized quad ([-1.0, 1.0] in X and Y) with normalized UVs [0.0, 1.0] using the currently-bound shader Binds the vertex position and UVs arrays to the given attribute array indices and draws the object using the bound shader

Parameters:

[in]	positionAttrib	the vertex attribute array index that represents position in the current shader
[in]	texcoordAttrib	the vertex attribute array index that represents 2D UVs in the current shader

void NvDrawQuad

(

GLuint

posIndex

)

Draw a 2D quad with a single vertex attribute.

Renders a normalized quad ([-1.0, 1.0] in X and Y) using the currently-bound shader Binds the vertex position array to the given attribute array index and draws the object using the bound shader

Parameters:

[in]

posIndex

the vertex attribute array index that represents position in the current shader

void NvDrawWireCube

(

GLuint

posIndex

)

Draw a wireframe cube with positions.

Renders a normalized cube ([-1.0, 1.0] in X, Y, and Z) as lines using the currently-bound shader Binds the vertex position array to the given attribute array index and draws the object using the bound shader

Parameters:

[in]

posIndex

the vertex attribute array index that represents position in the current shader
