We present a bump mapping method that requires minimal hardware beyond that necessary for Phong shading. We eliminate the costly per-pixel steps of reconstructing a tangent space and perturbing the interpolated normal vector by a) interpolating vectors that have been transformed into tangent space at polygon vertices and b) storing a precomputed, perturbed(More)
Programmable shading is a common technique for production animation, but interactive programmable shading is not yet widely available. We support interactive programmable shading on virtually any 3D graphics hardware using a scene graph library on top of OpenGL. We treat the OpenGL architecture as a general SIMD computer, and translate the high-level(More)
This thesis is an investigation of undergraduate physics students' descriptions of their learning experiences with respect to the lectures they attend. The work examines three connected areas; the effects of the language of instruction on learning in Swedish university physics lectures, students' experience of the equations presented to them in physics(More)
