So Thunderstruck just pointed out to me something I forgot to mention to anybody attempting to use the Library. By default the C code versions of the functions are compiled. You will see that this works but is slow compared to my demo. Inside the functions are #ifndef __ASM_CODE statements so I toggled the compiling of the assembly version by using a defined variable. To define the variable you just need to add -D__ASM_CODE to your gcc command inside your makefile. This will define __ASM_CODE and cause the ifndef statements to compile the assembly versions of the functions instead. I did this for two reasons. 1 to prove that the assembly versions of the functions were indeed faster and 2 I find it easier to write a new function in C and then convert it to assembly after I’m sure the function works.
Also, and this one is a little embarassing, I used a global camera variable for most of the functions. I mistakenly left the define of that variable inside my GameFunctions.h instead of putting it inside the G3d.h. So if you’re going to start a new project from scratch just add
camera cam;
to G3d.h somewhere and you should be good to go.
Thanks for trying it out and catching that Thunderstruck 🙂
I’m posting my makefile as well along with the ObjFileParser I wrote in java to import 3d Wavefront OBJ files.
The syntax to use the ObjFileParser is (from a command prompt)
java -jar ObjFileParser 50 3 filename.obj > output.h
The 50 is a scaling factor and can be anything > 0.
The 3 is the fixed point scale factor and should be 3 if your using my library as is.
This writes to standard out so > output.h will put the output into a file.
