scale_complex_pixeltexture.x3d

(.x3d scene, pretty-print source, statistics, info & logs, X3DOM Player)

Test scale field for PixelTexture mapping to complex geometry. Test browser ability to apply scales of (left to right) -4 -4, -2 -2, .5 .5, 2 2, and 4 4 to a PixelTexture consisting of a square checkerboard of blue (lower left quadrant), yellow (lower right), red (upper right) and green (upper left) mapped to the faces of complex geometry, mapping with default complex geometry mapping rules. The result (using complex geometry mapping rules) is (for the bottom face of the ElevationGrid, the side and bottom end cap of the Extrusion, and the front of the IndexedFaceSet) : a 4 X 4 reversed and inverted matrix of PixelTextures should appear on these faces in the first (far left) column. The second column should display a reversed and inverted 2 X 2 matrix of PixelTextures. The third geometry column should map a double sized PixelTexture and appear blue on all faces. The fourth column should disiplay a 2 X 2 matrix of right side up PixelTextures, and the fifth column should display a 4 X 4 matrix of PixelTextures. Opposite geometry faces should show reversd mapping, and side faces for the IndexedFaceSet should show smeared end pixels of the front and back faces.
