HaloMD - Intel Graphics Renderer

Managed to render a GLSL teapot into blood gulch (not related to any map objects)

 

Managed to... sortof... render over map objects

The map objects you've rendered over so far seem to be stationary. Following a moving object would be super cool - fantastic job so far, though. This is great!

I'm currently rendering over scen and vehi objects. The rotation is a bit odd on vehicles since I can't figure out how to get roll from the objects rotation.

I'm currently rendering over scen and vehi objects. The rotation is a bit odd on vehicles since I can't figure out how to get roll from the objects rotation.

Just typed this up. I got some of this information from http://www.euclideanspace.com and some from people in #macgamingmods IRC. Know that the last two columns of the matrix are backwards, the matrix has two rows instead of three, and pitch seems to be negative, so a lot of stuff I had to figure out on my own.

 

#include <math.h>

typedef struct Orientation {
    float yaw;
    float pitch;
    float roll;
} Orientation;

Orientation getObjectsOrientation(void *object) {
    float matrix_00 = *(float *)(object + 0x74);
    //float matrix_01 = *(float *)(object + 0x78);
    //float matrix_02 = *(float *)(object + 0x7C);
    float matrix_10 = *(float *)(object + 0x80);
    float matrix_11 = *(float *)(object + 0x84);
    float matrix_12 = *(float *)(object + 0x88);

    Orientation orient;
    orient.pitch = asin(matrix_10) * -1;
    orient.roll = atan(matrix_11 / matrix_12 * -1);
    orient.yaw = acos(matrix_00 / cos(orient.pitch));
    return orient;
}

You spin me right round, baby

Right round like a record, baby

Right round round round

Next challenge is to find the texture GLuint's from Halo's memory.

There also seems to be a bug with vehicles where the location is wrong (maybe a centroid or something instead of the base).

It's buggy but kindof works. I suspect I've found the cause of why Integrated Graphics aren't working properly in the first place too. 

Picture from laptop with Intel Integrated Graphics [without Shader Workaround]. The rock / buggy fern are rendered with the MD plugin.

I replaced Halos scen and bsp renderer with Electron. Here's it on integrated graphics:
