Developer's weekly reports


Progress Report for Eric Smith
Weeks ending: 11/11/94


HoverStrike
-----------
Downloaded and compiled speech compression
and synthesis programs for the TT, for
evaluation for use in the game.

Integrated general font routine into the game
and provided a scrolling text "puppet show"
while decompression is in progress.

Converted existing font blit code to use the
new font mechanism, and to properly center
proportional text.

General Jaguar
--------------
Added 1, 4, and 8 bit output options to tga2cry,
including palette construction code.

Updated tgainfo program to display info about
the number of colors used by a file.

Wrote a general font routine using the blitter
to do bit to pixel expansion.

Wrote font converters and downloaded public domain
fonts for use with the font routine.

Compared compression speeds of Brainstorm's JPEG
implementation and Atari's.

Merged Mike's MS-DOS version of tga2cry with my new
one, and gave the new version back to him.


Progress Report for Eric Smith
Weeks ending: 11/25/94


HoverStrike
-----------
Improved compression of bitmaps and cockpit.

Sped up font output by using phrase mode.


General Jaguar
--------------
Fixed bit-to-pixel expansion in the font code
for 1, 2, and 4 bit per pixel modes.

Implemented phrase mode blits for "direct copy"
fonts, and figured out the mysteries of the STEP
variables and the SRCENX bit.

Began work on a general C library for the Jaguar;
ported various routines from the MiNT library for
the ST to the Jaguar, and tested the new Brainstorm
tools.

Wrote test program to test blitter speed when blitting
from DRAM, GPU RAM, DSP RAM, and the CLUT.

Added File Access Table code to the NVRAM BIOS code.


Miscellaneous
-------------
Released a new version of MiNT.


Progress Report for Eric Smith
Weeks ending: 12/10/94


HoverStrike
-----------
Wrote tools to unpad and stretch Targa files (to
clean up art so that it's properly aligned for JPEG).

Revised puppet show code and credits display.

Added code to display an introductory message overlaid
on a spinning globe at start up time.

Fixed the fonts.


General Jaguar
--------------
Began work on Jaguar II texture mapping library.

Tracked down a blitter bug.

Fixed some bugs in the font generator program.

Translated NVM BIOS into assembly language to make
it fit into 2K.


Progress Report for Eric Smith
Weeks ending: 12/24/94


HoverStrike
-----------
Worked to find ways of speeding up the game, including
trying different blitting strategies, optimizing
the xgrid package, and sorting polygons.

General Jaguar
--------------
Fixed some bugs in the assembly version of
the NVM Bios.

Revised documentation for the NVM Bios.

Produced a ROMULATOR based NVM Bios emulator.


Weekly Report for Eric Smith
Week ending: 1/20/95


HoverStrike
-----------
Implemented shading of texture maps, by doing a
double blit (from DRAM to GPU RAM, and then from
GPU RAM to the screen). Experimented
with several shading strategies using both the
blitter ADDDSEL and SRCSHADE flags to find which
would work best for different texture maps and
worlds.

Assisted with some debugging of the code.


General Jaguar
--------------
Tested relative speeds of matrix multiplication
using the GPU MMULT and IMULTN/IMACN instructions.

Implemented a 68000 wireframe polygon renderer,
to test different clipping and transformation
strategies. The algorithms used here will later be
ported to the GPU for use in the Jaguar II polygon
renderer and demos.


Work Planned for Next Week

HoverStrike
-----------
I plan to convert the JPEG decompression code in
HoverStrike to use Brainstorm's new JPEG code. This
should result in an improvement in speed and ROM
space available.

Jaguar II Library
-----------------
I plan to add Gouraud shading to the 68000 renderer
and test different lighting algorithms.


WEEKLY REPORT for Eric Smith
Week ending: 1/27/95


HoverStrike
-----------
Added Brainstorm's JPEG code, and tested it by
compressing the title screens. The main texture
maps are still in a state of flux, so it has
been decided to leave them compressed the old
way until final texture selection has been made.

Found some more room in ROM (we were running
out, now we're not).

Jaguar II Library
-----------------
Added Gouraud shading (with in-scene and
out of scene (sunlight) light sources), plain
texture mapping, and Z buffering to the 68000
polygon renderer, and tested and debugged
these and the clipping algorithms.



WORK PLANNED FOR NEXT WEEK

HoverStrike
-----------
If the art is ready, I will convert all remaining
JPEG files to Brainstorm's format.

Jaguar II Library
-----------------
I plan to add (simple) shading to the texture
mapping code, and then to begin porting the renderer
to the GPU (which should result in a very large
speed improvement).



PROBLEMS

I've been running low on hard disk space, and periodically
have to spend time hunting through and backing up older
files. That has worked so far (at some cost in productive
time), but there aren't many "old" files left on my disk!


WEEKLY REPORT for Eric Smith
Week ending: 2/03/95


HoverStrike
-----------
Assisted in debugging.

Revised my font display program and assisted
in searching for new fonts for title screen/etc.
Downloaded Postscript font conversion utilities.

Downloaded Hubble Space Telescope images for use
as backgrounds.

Finished Brainstorm JPEG code.


General Jaguar
--------------
Added -crop option to the tga2cry and tgastretch
utilities (to allow selection of a smaller window
from a large picture).


Jaguar II Library (3D renderer)
-------------------------------
Fixed bugs in perspective mapping and clipping.

Began translation to GPU assembly.


WORK PLANNED FOR NEXT WEEK

HoverStrike
-----------
Assist in debugging and tweaking, as necessary.


Jaguar II Library
-----------------
Continue translation of 68000 polygon renderer to
GPU assembly language.


PROBLEMS

Nothing noteworthy.

Continue translation of 68000 polygon renderer to
GPU assembly language.

HoverStrike
-----------
Assist in debugging and tweaking, as necessary.


Jaguar II Library
-----------------
Continue translation of 68000 polygon renderer to
GPU assembly language.


PROBLEMS

Debugging of the NVRAM BIOS was made slightly harder
by the small number of PAL machines in the building.
We could certainly use a PAL machine+TV dedicated
to software development.
