421 * * the geometry shader, if active;
422 * * the tessellation evaluation shader, if active and no
423 * geometry shader is active;
424 * * the vertex shader, otherwise
426 * and clamped to the implementation-dependent point size range. If
427 * the value written to gl_PointSize is less than or equal to zero,
428 * or if no value was written to gl_PointSize, results are undefined.
429 * If program point size mode is disabled, the derived point size is
430 * specified with the command
432 * void PointSize(float size);
434 * size specifies the requested size of a point. The default value
437 * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
438 * OES_tessellation_point_size specifications. To summarize: if the last
439 * stage before rasterization is a GS or TES, then use gl_PointSize from
440 * the shader if written. Otherwise, use 1.0. If the last stage is a
441 * vertex shader, use gl_PointSize, or it is undefined.
443 * We can combine these rules into a single condition for both APIs.
444 * Using the state point size when the last shader stage doesn't write
445 * gl_PointSize satisfies GL's requirements, as it's undefined. Because
446 * ES doesn't have a PointSize() command, the state point size will
447 * remain 1.0, satisfying the ES default value in the GS/TES case, and
448 * the VS case (1.0 works for "undefined"). Mesa sets the program point
449 * mode flag to always-enabled in ES, so we can safely check that, and
450 * it'll be ignored for ES.
