DISPLAY

3D Renderer for the TRS-80 Color Computer

Rotating Image Animation

Disk Image and Source Code

The disk image contains three versions:

  • DISPLAY.BAS / DISPLAY.BIN / DISPLAY.ASM

    • A gently modified version of the original code to make it work with Microsoft Disk BASIC
    • From BASIC, type RUN "DISPLAY"
  • DISPLAY2.BAS / DISPLAY2.BIN / DISPLAY2.ASM

    • Allows you to rotate about multiple axes simultaneously
    • Moves common variables to the direct page and adds support for the 6309 processor
    • Runs much faster than the original
    • From BASIC, type RUN "DISPLAY2"
  • DISPLAY3.BAS / DISPLAY3.BIN / DISPLAY3.ASM

    • Requires a Color Computer 3
    • Assembly converted to a modern standard
    • From BASIC, type RUN "DISPLAY3"

To Use

  • Mount the disk image and RUN one of the three versions
  • Type LOAD"DIAMOND" and press ENTER
  • Try: X, Y, Z, SHIFT-X, SHIFT-Y, SHIFT-Z, ARROW KEYS, S (smaller) and B (bigger)
  • On the CoCo 3 version, try the ENTER key
  • To exit display mode, press the @ key
  • Type HELP to learn more
