WebThe cylinder wall occurs when s= r. The enddisks occur when jtj= h=2. The choice of U and V is arbitrary, but the inersection queries between cylinders are independent of this choice. A quadratic equation that represents the cylinder wall is (X C)T(I WWT)(X C) = r2 with boundedness speci ed by jW (X C)j h=2. WebIf the triangles are co-planar, they are projected onto the axis-aligned plane where the areas of the triangles are maximized. Then a simple two-dimensional triangle-triangle overlap test is performed. First, test all closed edges of T 1 for inter-section with the edges of T 2. If any intersection is found, then the triangles intersect. 2
