NAME¶
glMultiDrawElementsBaseVertex - render multiple sets of primitives by specifying indices of array data elements and an index to apply to each indexC SPECIFICATION¶
void
glMultiDrawElementsBaseVertex(GLenum mode,
const GLsizei *count,
GLenum type,
const GLvoid * const *indices,
GLsizei drawcount,
const GLint *basevertex);
PARAMETERS¶
modeSpecifies what kind of primitives to render. Symbolic
constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP,
GL_LINES, GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY,
GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES,
GL_TRIANGLE_STRIP_ADJACENCY, GL_TRIANGLES_ADJACENCY and
GL_PATCHES are accepted.
count
Points to an array of the elements counts.
type
Specifies the type of the values in indices. Must
be one of GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT, or
GL_UNSIGNED_INT.
indices
Specifies a pointer to the location where the indices are
stored.
drawcount
Specifies the size of the count, indices
and basevertex arrays.
basevertex
Specifies a pointer to the location where the base
vertices are stored.
DESCRIPTION¶
glMultiDrawElementsBaseVertex behaves identically to glDrawElementsBaseVertex(), except that drawcount separate lists of elements are specifried instead. It has the same effect as:for (int i = 0; i < drawcount; i++) if ( count[i] > 0) glDrawElementsBaseVertex( mode, count[i], type, indices[i], basevertex[i]);
NOTES¶
glMultiDrawElementsBaseVertex is available only if the GL version is 3.1 or greater. GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available only if the GL version is 3.2 or greater.ERRORS¶
GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_VALUE is generated if drawcount is negative. GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object's data store is currently mapped.VERSION SUPPORT¶
