Polygon rasterization with edge function

WebTo get the UV coordinate of the point on the edge, just linear interpolate between the two UV values of the points using the percentage you just found. For a point inside the triangle, first find the UV coordinate of the point projected onto one of the edges as above, then do the same thing for the other edge but this time, when linear interpolating, use the UV … WebA r e a = A. x ∗ B. y − A. y ∗ B. x. From a practical point of view, all we need to do now is test the sign of the edge function computed for each edge of the triangle and another vector …

WebAug 22, 2016 · 2. As a workaround, you could enlarge your river (buffer tool) with half pixel width to make sure that there is always at least one pixel that is covered by more than half of the polygon. The problem is that you might then have more pixels than expected. Therefore you can apply the " thin " function afterward to reduce the width to a single pixel. WebDec 1, 2024 · You can control the transparency of an object using the alpha function or by setting properties of the object related to transparency. Some graphics objects support using a different transparency value for the faces versus the edges of the object.
