);

in indx Vertex attribute index number
in x Vertex attribute value
in y Vertex attribute value

Return Values

No values are returned.

Description

Sets vertex attributes using GLfloat-type values.

Set index to a value that is greater than 0 and at least one less than the value that can be obtained by glGetIntegerv with GL_MAX_VERTEX_ATTRIBS specified. Call this function when using the same vertex attribute values for all vertices. The values set by this function are used when a vertex attribute array has been disabled by glDisableVertexAttribArray.

The values specified by x and y are given as the x and y components, respectively, to the vertex shader's input registers. Values of 0 and 1 are respectively given for z and w.

This function generates the following errors.

GL_INVALID_VALUEThe index argument was set to an invalid value.
