This chapter describes the Quadrilateral Mesh test programs. The following is defined for each test program:
  • Name of the test program
  • Test types (See the section "Denizen Test Types" on page 2 for the different test types.)
  • Description of the test program
  • Attributes tested by the program
  • Operators tested by the program
  • Output from the test program
· qm_col_norm
Test Types:INDEX, SM
Description:Same single quadmesh rendered with all the 3D possible point types, all the possible fill styles, a single ambient light source, and all the possible illumination types. The outer loop sets the interior styles, the next loop sets the illumination types, the next loop sets the point type, and the final loop sets the facet data.
Attributes Tested: See Table 20-1, Column A at the end of this chapter.
Operators Tested: xgl_object_set 
                    xgl_object_get
                    xgl_quadrilateral_mesh
Output:             When the point type includes color information and the
illumination is per vertex, expects a rainbow like a candy cane for the edge for hollow or the complete interior for solid where the candy cane/rainbow is red, green, yellow, dark blue, purple, and light blue. When illumination is per vertex and the point type does not involve color but the facet type does, expects the facet color, which is green for the edge in the hollow case and the complete interior for the solid case. Otherwise when illumination is per vertex, the point type does not involve color, and the facet type is none or involves normal information only, expects the interior color set, which is red for the edge in the hollow case and the entire interior for the solid case. For the empty interior fill style, expects the background color.
· qm_col_norm_rgb
Test Types:RGB, SM
Description:Same single quadmesh rendered with all the 3D possible point types, all the possible fill styles, a single ambient light source, and all the possible illumination types. The outer loop sets the interior styles, the next loop sets the illumination types, the next loop sets the point type, and the final loop sets the facet data.

Output:             When the point type includes color information and the
illumination is per vertex, expects a shaded coloring that blends into green for the edge for hollow or the complete interior for solid. When illumination is per vertex and the point type does not involve color but the facet type does, expects the facet color, which is blue for the edge in the hollow case and the complete interior for the solid case. Otherwise when illumination is per vertex, the point type does not involve color, and the facet type is none or
involves normal information only, expects the interior color set, which is red for the edge in the hollow case and the entire interior for the solid case. For the empty interior fill style, expects the background color.
· qm_cull_rgb
Test Types:RGB, SM
Description:Draws RGB quad mesh composed of four facets; two on the diagonal from left to right are back facing, while the two on the opposite diagonal are front facing, with different face-culling modes (none, front, back).

Output:             When the quadmesh is front facing, that is, the z
component of its normal is less than 0.0, and the cull mode is FRONT, the expected color is the background, which is black. When the quadmesh is front facing and the cull mode is anything except FRONT, the expected color is the front surface color, which is purple. When the quadmesh is not front facing, that is, the z component of its normal is greater than or equal to 0.0, and the cull mode is FRONT, the expected color is the back surface color, which is yellow. Any other cull mode for a back-facing quadmesh is expected to be the background color, which is black.

Attributes Tested: See Table 20-2, Column C at the end of this chapter.
Operators Tested: xgl_object_set 
                    xgl_object_get
                    xgl_quadrilateral_mesh
Output:             Expects the front surface color, which is red for the edge
color when both the facet data and the point type have no color information. Expects the facet color for the individual facets, which are red, green, blue, and yellow for the edge colors when the facet data has color information.

Output:             Expects candy cane edges of red, green, yellow, dark blue,
purple, and gray when the point type contains color information. Expects the front surface color for the edge color, which is red when both the facet type and the point type contain no color information. Expects the facet color for the edge color, which is red, green, blue, and yellow for the ordered facet list of quadmeshes when only the facet data contains color information.

Output:             Expects a rainbow of colors in the edges of red, yellow,
light blue, purple, and gray when the point type contains color information. Expects the front surface color for the edge color, which is red when both the facet type and the point type contain no color information. Expects the facet color for the edge color, which is red, green, blue, and yellow for the ordered facet list of quadmeshes when only the facet data contains color information.
· qm_cull
Test Types:INDEX, SM
Description:Draws INDEX quadmesh composed of four facets; two on the diagonal from left to right are back facing, while the two on the opposite diagonal are front facing, with different face-culling modes (none, front, back)
Attributes Tested: See Table 20-2, Column B at the end of this chapter.
Operators Tested: xgl_object_set 
                    xgl_quadrilateral_mesh
Output:             When the quadmesh is front facing, that is, the z
component of its normal is less than 0.0, and the cull mode is FRONT, the expected color is the background, which is black. When the quadmesh is front facing and the cull mode is anything except FRONT, the expected color is the front surface color which is red. When the quadmesh is not front facing, that is, the z component of its normal is greater than or equal to 0.0, and the cull mode is FRONT, the expected color is the back surface color, which is green. Any other cull mode for a back-facing quadmesh is expected to be the background color, which is black. The normal appearance of the quadmesh with culling set to NONE is a four-faceted quad with the left to right facets on the diagonal green and the opposite diagonal facets red.
· qm_hlhsr
Test Types:INDEX, SM
Description:Renders two sets of the same quadmesh with different z values and expects to view the quadmesh with the smaller z depth. The first set of quadmeshes are set up with a front surface color of yellow, while their exact counterparts have a front surface color of light blue. The depths for the same quadmesh with different colors are such that the first quadmeshes rendered are expected, the second quadmeshes rendered are expected and again the second quadmeshes rendered are expected. Finally, renders a quadmesh where two of the vertex are overlapping.

Output:             Two sets of quadmesh. The top one is composed of a
single square, and the bottom one is composed of two squares. Their color alternates between red and green. The final frame is a single red quadmesh.
