well here is what I have.. maybe you can tell me whats wrong..

getting the light values



void RenderShadows(){
float tmp[16];
//for( int i = 0; i < NUMLIGHTS; i++ ){
...

so if I understand you right it would be
projection[camera] * modelview[camera] * inverse( projection[light] * modelview[light] ) right??

edit: That did not seem to work right...looks as if it...

Hi,
So this is a stupid question but I cant seem to get it right.
I am trying to draw a light's frustum by drawing a unit cube (-1, -1, -1 ) -> (1,1,1) yet I cant seem to get the matrix right.
I...

The gpu should use the highest precision possible already...

So its not letting me edit my last post, but heres what I have now, and the error still exist.

Depht map, GL_DEPTH_COMPONENT, GL_LINEAR, GL_FLOAT (not erroring now, so idk..)
vsm_tex (stores the...

How do I go about doing this in a shader??
EDIT: also just switched everything to GL_UNSIGNED_BYTE with GL_LINEAR, and the same thing happens

I am using gl_NEAREST right now, I cannot use anything else due to the fact that im using GL_FLOAT (32F) so they do not support hardware filtering for speed.

Hey guys, I had this problem before and managed to solve it however doing the same steps I cannot solve it this time, so I ask you again if you have any idea why these textures are not coming out...

nevermind lol

Oh man, just got my bug fixed with my shadow maps. Looking to implement VSM's so that tut will be GREAT. thanks a lot!

Worked great. Got that error fixed. Its producint REALLY hard shadows right now, that are aliased even at higher resoultions (1024x1024 when the normal screen is 640x480 ) but I'll fix / work on this...

Gah still stuck with this error.. -___- any other ideas?

changed from GL_CLAMP to GL_CLAMP_TO_BORDER and now I have this.

looks pretty good, I believe the multiple levels of...

not sure if I got the projection inverse right, I took the projection matrix muled it by the modelview, grab that matrix and inversed it.
if this is right then the unit cube is off

I am sorry, and probably seem dumb, but I really dont understand much of what you guys are saying lol.
I have viewed the shadow map and it is coming out right, also moveing the camera near the...

Sorry I dont get what you mean.

Hey guys,
so im looking to implement cascading shadow maps, thought I am currently doing a very basic single map method (my first time doing shadows ) and have come across a error I cant fix.

...

Thanks, Ill check out nvidia's CSM stuff, just read the gpu gems 3 article on PSSM's..
Thanks for the help

I was looking at CSM's (btw is there anything different between CMS's and PSSM's? they seem the same )
I've also heard it is possible to combine VSM's and PSSM's to create something called PSVSM. I...

Sorry I did mean shadowing both times. Thanks for the information, Im suprized that there is not one stand out method of shadows for deferred shading thought.. Anyways I think im going to look itno...

Hi,
I have a simple and small question, just woundering what method of shading would be best suited for deffered rendering. Also could someone provie me with a link to the pro's and con's of each...

äh of course. The default in OpenGL is, that you look along the negative Z-Axis. So normly z-Valus are between 0 and -1.[/QUOTE]

Hah, you know, as soon as you hear it - it makes so much since......

Honestly I cant say.I've never made a shader loader from a string, rather I just load them from files, and nothing stands out besides your use of ARB (if you can use 2.1 and glsl 1.2 then you dont...

It seems like it is a simple overflow to me, but I didnt really read much of the code.. try adding a null terminator '\0' to the end, I had to do this to stop such a error in one of my parsers...

How exactly do i check this? Also how do these become corrupt? Didnt know it was possible.
EDIT: Just did a more extensive test, and it appers the value is always <0.0 and not == 0.0..
