Private Fields

csColor*	colors If uv_coords is given then this can be an optional array of vertex colors
int	num_vertices Number of vertices.
csColor*	static_colors This array contains the static colors
csVector2*	uv_coords If the following arrays is non-NULL then this polygon is drawn using a different technique (all previous mipmap and lightmap stuff is ignored)

Private Methods

	csGouraudShaded () Constructor.
virtual	~csGouraudShaded () Destructor.

Inherited from csPolygonTextureType:

csVector2* uv_coords

If the following arrays is non-NULL then this polygon is drawn using a different technique (all previous mipmap and lightmap stuff is ignored). The polygon will be drawn with perspective incorrect texture mapping and (in the future) Gouroud shading. The following array specifies the u,v coordinates for every vertex of the polygon.

csColor* colors

If uv_coords is given then this can be an optional array of vertex colors. If this array is given then gouraud shading is used. Otherwise flatshading.

csColor* static_colors

This array contains the static colors. It is used in combination with 'colors'. 'colors=static_colors+dynamic_lights'.

int num_vertices

Number of vertices.

csGouraudShaded()

Constructor.

virtual ~csGouraudShaded()

Destructor.

virtual int GetTextureType()

Return a type for the kind of texturing used.

void Setup(int num_vertices)

Setup this lighting structure with the rignt number of vertices. If use_gouraud is true we will also use gouraud shading. This function is guaranteed not to do anything if the number of vertices is already correct.

void EnableGouraud(bool g)

Enable/disable gouraud. This function is guaranteed not to do anything if gouraud shading was already enabled and it is enabled again.

void SetUV(int i, float u, float v)

Set an (u,v) texture coordinate for the specified vertex of this polygon. This function may only be called after all vertices have been added. As soon as this function is used this polygon will be rendered using a different technique (perspective incorrect texture mapping and Gouroud shading). This is useful for triangulated objects for which the triangles are very small and also for drawing very far away polygons for which perspective correctness is not needed (sky polygons for example).

void Clear()

Clear all (u,v) and color information

csVector2* GetUVCoords()

Get the pointer to the vertex uv coordinates.

csColor* GetColors()

Get the pointer to the vertex color table.

csColor* GetStaticColors()

Get the pointer to the static vertex color table.

void AddColor(int i, float r, float g, float b)

Add a color to a static array color entry

void AddDynamicColor(int i, float r, float g, float b)

Add a color to a dynamic array color entry

void SetDynamicColor(int i, float r, float g, float b)

Set a color in the dynamic array

void ResetDynamicColor(int i)

Reset a dynamic color to the static values

void SetDynamicColor(int i, csColor& c)

Set a color in the dynamic array

void SetColor(int i, float r, float g, float b)

Set a color in the static array

void SetColor(int i, csColor& c)

Set a color in the static array
