Hmm.. it appears to be YET ANOTHER matrix problem. :devil:

An interesting effect:
When I comment out the last line in matrix multiplication, the zooming in the game works perfectly, but the mario logo, text, and portraits do not work.


void modelview_mul (float m[4][4])
{
float m_src[4][4];
memcpy (m_src, rdp.model, 64);

for (int i=0; i<4; i++)
{
for (int j=0; j<4; j++)
{
rdp.model[j] =
m_src[0] * m[j][0] +
m_src[1] * m[j][1] +
m_src[2] * m[j][2]/* +
m_src[3] * m[j][3]*/;
}
}
}

or even more specific, if I don't add the projection matrix's z:

v.x = x*rdp.proj[0][0] + y*rdp.proj[1][0] + z*rdp.proj[2][0] + rdp.proj[3][0];
v.y = x*rdp.proj[0][1] + y*rdp.proj[1][1] + z*rdp.proj[2][1] + rdp.proj[3][1];
v.z = x*rdp.proj[0][2] + y*rdp.proj[1][2] + z*rdp.proj[2][2];// + rdp.proj[3][2];

Great thread, but it's getting a bit big. Mind if I split it into two threads?

Sure, go right ahead.

I don't believe it!!! I should have listened to myself earlier. I fixed the zooming problem. You ARE supposed to divide by w instead of z during the 3d->2d stage.

Now princess shows up, and also it doesn't get too close to mario when in mario camera mode.

(don't ask me HOW I figure all these strange things out, it just kinda happens, and very quickly at that :D)

Alright, first time I'm splitting a thread. Let's hope it works okay. :)

Great work Dave!

Works very well on my V3 2000, PIII 550Mhz and WinXP.

Quick question:

What's the next game you are going to concentrate on?

Dave2001,

The modelview matrix is handled a little differently then the projection matrix.

the modelview should only deal with x,y and z values while the projection matrix deals with x,y,z and w values.

maybe this will help out.

Cool

Now if only one could do something similiar to ye olde PSX. Unfortunately you are stuck with there GTE seperate from the GPU (heh).

Well Dave if you have any questions feel free to express your anger.. err ;) express them here ;)

at least we know it's not a HYDRAHLE thing.
(what if dave2001 had said, "I'm developing a new plugin for Glide2x users!!! it can run Mario64 very well!!! too bad I feel that it doesn't need to be released though")

on the flip side, very good work dave2001!
