Cel-shaded TMD Rendering Example (plus low-level GTE stuff)

Well... I somehow managed to achieve what was thought to be impossible to do on the PlayStation and that is cel-shading
:
Basically, what I did was using the resulting vertex colors after passing through light source calculation as texcoords which then maps to a texture of 3 color tones... Its essentially the same technique used in many games that utilized cel-shading before pixel shaders became dominant on graphics processors.
This example also demonstrates the use of low-level GTE macros as a faster alternative to RotTransPers3() and NormalColorCol3() which are essential to writing fast custom 3D graphics routines.

Good works dear LameGuy3D. I would like to make graphics with this technique

I know this is a very old thread, but it would be awesome if someone could modify this to make environment mapping textures.
I tried with a simple "asteroid" shape... but my programming and math skills are really bad.
Maybe LameGuy64 will add env-mapping to PSn00bSDK.
EDIT: I copied one of the samples in the psyq folder and I got it
. I plan to make a little library and a demo using psyq. But if PSn00bSDK is updated, maybe I will use it.

Studying this example right now. Here is the modified makefile I came up with, based on yours LameGuy64, in order to compile in Linux :
Be mindful that you may have to change the paths in the following script.
Code: Select all
# Run this makefile in GNU/Linux.
WORKING_DIR = TMDCEL
#16-bits DOS exes run in Dosbox
RSDLINK = "C:\PSYQ\BIN\RSDLINK.EXE"
DMPSX = "C:\PSYQ\BIN\DMPSX.EXE"
CPE2X = "C:\PSYQ\BIN\CPE2X.EXE"
TARGET = main
ADDRESS = 0x80010000
CFLAGS = -O3 -Wall
all:
# Convert suzanne RSD to TMD
echo @echo on > dosbox.bat
echo D: >> dosbox.bat
echo cd "D:\$(WORKING_DIR)" >> dosbox.bat
echo $(RSDLINK) -s 30.0 -o "SUZANNE\SUZANNE.TMD" "SUZANNE\SUZANNE.RSD" >> dosbox.bat
echo exit >> dosbox.bat
dosbox -c "D:\$(WORKING_DIR)\DOSBOX"
rm dosbox.bat
# Convert TMD to C
bin2h.exe suzanne/suzanne.tmd suzanne/suzanne.c tmd_suzanne -nosize
# build tmdcel.obj
CCPSX.EXE $(CFLAGS) -c tmdcel.c
# Pre-process tmdcel.obj with dmpsx
echo @echo on > dosbox.bat
echo D: >> dosbox.bat
echo cd "D:\$(WORKING_DIR)" >> dosbox.bat
echo $(DMPSX) tmdcel.obj >> dosbox.bat
echo exit >> dosbox.bat
dosbox -c "D:\$(WORKING_DIR)\DOSBOX"
rm dosbox.bat
#build CPE and SYM
CCPSX.EXE -Xo$(ADDRESS) $(CFLAGS) main.c loadtim.c tmdcel.obj suzanne/suzanne.c celmap.c -o$(TARGET).cpe,$(TARGET).sym
# Convert CPE to PSX EXE
echo @echo on > dosbox.bat
echo D: >> dosbox.bat
echo cd "D:\$(WORKING_DIR)" >> dosbox.bat
echo $(CPE2X) MAIN.CPE >> dosbox.bat
echo exit >> dosbox.bat
dosbox -c "D:\$(WORKING_DIR)\DOSBOX"
rm dosbox.bat
Psy-Q is setup with Wine as per
https://github.com/electrobs/PSYQ_Examples and you have to put this in the 'autoexec' section of dosbox.conf :
Code: Select all
[autoexec]
# Lines in this section will be run at startup.
# You can put your MOUNT lines here.
# this is where the psyq folder is
MOUNT C ~/.wine/drive_c
# this is the folder where I unzip the examples
MOUNT D ~/build/PSYQ_Examples
# change to C:
C:
#go to the binary folder
cd psyq\bin
#clear screen
CLS
Additionally, you have to get bin2h.exe here :
https://github.com/apiraino/psx_tapper/ ... /bin2h.exe
and put it in '~/.wine/drive_c/psyq/bin' .
Hope it helps someone !
