ABSTRACT
The pfman language was developed specifically for real-time execution on the PixelFlow graphics machine [130]. It is also a high-level C-like language, quite similar to RenderMan.
13.1 Logical Model The logical model for PixelFlow was presented earlier to guide our initial presentation of the logical model diagrams in Chapter 4. We reproduce this diagram here for reference (Figure 13.1). We will point out this time around which procedural stages were actually implemented. Surface and light shaders were implemented and well-utilized by users of the PixelFlow system. Primitive and interpolate stages were also implemented but were not as effective, and were never really used.
