- All Implemented Interfaces:
- java.lang.Cloneable
public class UniformTriangle
- extends RenderingTriangle
UniformTriangle is a subclass of RenderingTriangle, which represents a triangle whose
properties are uniform over the entire triangle.

Method Summary |
double |
getDisplacement(double u,
double v,
double w,
double size,
double t)
Get the displacement for a point on the triangle. |
void |
getTextureSpec(TextureSpec spec,
double angle,

Given the barycentric coordinates for a point in the triangle, build a TextureSpec
describing the properties of the triangle at that point. |

getTransparency(RGBColor trans,
double angle,
double u,
double v,
double w,
double size,
double t)
Same as above, except only return the transparent color. |
void |

UniformTriangle

int v2,
int v3,
int n1,
int n2,
int n3)
setMesh
public void setMesh(RenderingMesh mesh,
TextureMapping map,
int index)
- Set the mesh that this triangle is part of. This is automatically called when the
triangle is added to the mesh.
- Overrides:
setMesh
in class RenderingTriangle
- Parameters:
mesh
- the RenderingMesh this triangle belongs tomap
- the TextureMapping for this triangleindex
- the index of this triangle within the mesh
getTextureSpec
public void getTextureSpec(TextureSpec spec,
double angle,
double u,
double v,
double w,
double size,
double t)
- Description copied from class:
RenderingTriangle
- Given the barycentric coordinates for a point in the triangle, build a TextureSpec
describing the properties of the triangle at that point. The properties should be
averaged over a region of width size.
- Specified by:
getTextureSpec
in class RenderingTriangle
getTransparency
public void getTransparency(RGBColor trans,
double angle,
double u,
double v,
double w,
double size,
double t)
- Description copied from class:
RenderingTriangle
- Same as above, except only return the transparent color. This can save time in cases
where only the transparency is required, for example, when tracing shadow rays.
- Specified by:
getTransparency
in class RenderingTriangle
getDisplacement
public double getDisplacement(double u,
double v,
double w,
double size,
double t)
- Description copied from class:
RenderingTriangle
- Get the displacement for a point on the triangle.
- Specified by:
getDisplacement
in class RenderingTriangle
