A method, apparatus, and article of manufacture enable the creation and display of a radial tessellation. A single source image is selected and a radial tessellation creation feature is activated. A triangular sector of the source image is specified and transferred to a texture buffer of a graphics processing unit (GPU). A radial tessellation is created using the GPU by drawing the triangular sector on a destination image, repeatedly flipping and drawing the triangular sector along a leading edge of the triangular sector to create a closed polygon, and further flipping and drawing the triangular sector onto the destination image to create outer rings around the closed polygon and filling the destination image. |
