Member Function Documentation

virtual void GlsPolygon::Draw ( GlsStateManager &  gl,
const GlsFloat64  time 
)
virtual

Draws this polygon

Parameters
glGL State manager for OpenGL into which polygon is drawn
timethe elaspsed time in seconds since program start
Precondition
time >= 0.0
Postcondition
polygon is drawn to OpenGL if visible and not blinked off

Implements GlsDisplayObject.

virtual void GlsPolygon::OffsetTexture ( const GlsVector2D &  offset)
virtual

Offset the texture on the object

Parameters
offsetx, y offset for texture
Precondition
offset.IsValid()
Postcondition
offset is added to the texture coordinates

Implements GlsRenderObject.

void GlsPolygon::SetVertex ( const GlsUInt32  index,
const GlsTextureVertex &  vertex 
)

Set one of the vertices in the polygon

Parameters
indexindex of desired vertex
vertexnew value of desired vertex
Precondition
index is less than the number of vertices in the polygon, vertex.IsValid()
Postcondition
vertex at desired index has new value
