This is a collection of three test plug-ins with source code, project files, and sample output which demonstrate why an IXP can't handle tracking a light when secondary motion particle systems are running in the same Video Post frame. Both working and non-working project files are included, with sample output from both and with versions of an AXP both without and with the offending instructions, respectively, are included. All source code included. File summary list and description included. The Petersons/Sisyphus LIB 1 – IPAS Usage [74461,157] Eric&AudreyPeterson FREESXPS.ZIP Bin, Bytes: 110955 Title : Free SXP Set from SISYPHUS Keywords: 3DS 3D STUDIO SXP XWAVE RIPPLE WAVE FREEWARE Two SXPs: RIPPLE and XWAVE. Ripple creates time- and distance-based animated, amplitude enveloped concentric travelling ripples. Dripping water? Ripple will handle the surface. Xwave handles interfering linear waves, also time-based and fully parameterized. Xwave provides some truly bizarre fuzzy quilt-like patterns with it's cross-waves interference patterns. Illustrated manual included in WordPerfect for Windows 6, Microsoft Word 5 formats and an ASCII text file. (Approx DL 2400 baud: 7:00; 14400 baud: 2:00) LIB 23 – *MM Developers [74461,157] Eric&AudreyPeterson SXPBUMPS.ZIP Bin, Bytes: 18518 Title : How SXP Bump Mapping Works Keywords: SISYPHUS SXP TECH NOTES CALCULUS GRADIENTS DERIVATIVES This is a text file and a simple SXP with both compiled and source code. The text file describes in detail how to set up good bump mapping algorithms and what trade-offs are involved in the formulation of algorithms with respect to numerical versus analytical techniques. The technical discussion assumes an elementary understanding of first year differential calculus, specifically the definition and meaning of partial derivatives of functions in multiple independent variables.
