wow, because of you I now have projectors for my spell casting. You have helped me solve a long time problem, and saved me a good amount of money.

Thankyou.

You are our hero!
I´ll send you some screens.

this is great!
question though... the projection works great and all, no probs there, but shadows dont seem to be working on this pc (work computer) though on my laptop (which specs are WAAAAAAAAAAAAY lower) it runs fine, any idea why they dont show up ?

(im using example 7. PT Spotlight with Shadow Mapping)

specs (of both machines) are:

Work PC:
win XP SP2
intel core 2 extreme (quadcore) 3.0 GHZ
4 gig Ram
ATI radeon 8800GTX 768MB

Laptop
win XP SP2
dual core (not a core 2 duo) 1.7 GHZ
1 gig Ram
ATI x1600 256MB

as you can see, both should work fine, i wouldnt have been surprised if thee laptop wouldnt work, but the monster-pc doesnt work... that's weird!

got any idea how to fix this (might be the 1024x1024 render target? how do we make that smaller if needed, so it's 24bit instead of 32bit).

regards,

I made a mistake, when looking at the version of A7 I using, I looked at about
in SED 7.06, instead of WED 7.07. Sorry about the confusion.

Ello:
This is the same as in the demo, except a few shaders were mistakenly set to be
compiled as VS 2.0 instead of 1.1.

Emre:
If you can not use Lite-c's "matViewProj", you can create this yourself like this.
Code:

---

  
//REPLACE THIS LINE
mat_set(mtlSpotlit.matrix,matViewProj);	  // store the transformation matrix to the material
 
//WITH THIS CODE
float my_matVP[16] = { 0.0, 0.0, 0.0, 0.0, 0.0,0.0,0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 };
mat_set(my_matVP,matView);
mat_multiply(my_matVP,matProj);
mat_set(mtlSpotlit.matrix,my_matVP);
 

---

Otherwise, it would be very hard to write this in C-Script (I know I said you
could), because c-script dosent support materials for views.

Helghast:
Yeah that is strange! To try a smaller resolution shadowmap, just change
bmap = "#1024x1024x14"; to
bmap = "#512x512x14"; or
bmap = "#256x256x14";

Grafton, this is so freaking awesome of you! THANKS!
I was able to convert the pixel shader examples to C-Script format, but I can't figure out a couple of things with the projection shader ones.

Could anyone help me convert this code to C-Script (wdl)? I've done most of it but I'm not sure how to change these lines:

function mtlProjection_event() // adjust matrices to size of bitmaps and pass to "matMtl" and "matEffect"
{
// create a transformation matrix
float pTexAdj[16] = { 0.5, 0.0, 0.0, 0.0, 0.0,-0.5, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0 };
// Adjust projection matrix for texture size
pTexAdj[12] = 0.5 + (0.5/(float)bmap_width(projectiontex));// store bitmap diminsions into matrix
pTexAdj[13] = 0.5 + (0.5/(float)bmap_height(projectiontex));
// Store the transformation matrix to the materials then adjust the matrix with the bitmap size
mat_set(mtlSpotlit.matrix,matViewProj); // store the transformation matrix to the material
mat_multiply(mtlSpotlit.matrix,pTexAdj); // adjust the matrix with the bitmap size
}

.......

function init_stages()
{
ProjectionView.stage = camera; // so projection is not lagging one frame behind
}

.......

As far as I can tell, these lines are the only thing that needs to be changed. I don't really know much about shader programming, otherwise I'd be able to do it myself. If someone could help me I'd be extremely grateful.

Thanks in advance!

Thanks again Grafton!
But child flags not working in the c-script.
VIEW ProjectionView =
{
material = mtlProjView;
flags = VISIBLE;
}
---------------------------------
< material = mtlProjView;>
Example.WDL 148:0 (): Keyword unknown ProjectionView material

< }>
Example.WDL 151:-1 (): Syntax error - ProjectionView
---------------------------------

Can somebody convert "example 5" to c-script please?

Great contribution! Many have been waiting for something like this

Me too I'd be interested in a c-script working version! I'd compensate such a conversion by donating both my model packs to the "convertor"

Thanks!

Thanks for your work.. this is awesome! I have some questions, though:

• does the shader work for multiple projectors, too?
• this is a perspective projector.. are you able to make an orthograpic projector as well?

Thanks for your work!!

cool, i'll try that when i get back to work ^_^

in the meantime im wondering, how can i change the colour of the shadow pixel?
(im on my laptop, which has shadows working, so i can develop a bit here )
I did find how i could change the environmental fog to be more dense etc, but not the shadow color... then again im a complete shader noob, and never worked in lite-c yet :O but this is so gonna get me started!!

again, thanks

regards,

Tested it, it works great

Cheers
