NAME¶
glDrawElementsInstancedBaseInstance - draw multiple instances of a set of elements with offset applied to instanced attributesC SPECIFICATION¶
void
glDrawElementsInstancedBaseInstance(GLenum mode,
GLsizei count, GLenum type,
const void * indices,
GLsizei primcount,
GLuitn baseinstance);
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
Specifies the number of elements to be
rendered.
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.
primcount
Specifies the number of instances of the
specified range of indices to be rendered.
baseinstance
Specifies the base instance for use in
fetching instanced vertex attributes.
DESCRIPTION¶
if (mode, count, or type is invalid ) generate appropriate error else { for (int i = 0; i < primcount ; i++) { instanceID = i; glDrawElements(mode, count, type, indices); } instanceID = 0; }
