    OpenGL ES Extension #??

Dependencies

    Requires OpenGL ES 3.0

    Written against the OpenGL ES 3.0 specification.

Overview

    This extension defines behavior when the type parameter of
    VertexAttribPointer has mismatched integer signedness with
    the shader's attribute.

New Procedures and Functions

    None

New Tokens

    None

Additions to the OpenGL ES Specification

    Add after paragraph 6 of section 2.9 "Vertex Arrays" (beginning with
    "When values for a vertex shader attribute variable are sourced..."):

    If the generic attribute is specified by VertexAttribIPointer with an
    unsigned type for base signed integer type attributes, or by a signed
    type for base unsigned integer type attributes, the values loaded
    into the shader attribute are reinterpreted as the corresponding
    signed/unsigned type.

New State

    None

Conformance Tests

    TBD

Issues

    None
