Projection Flashlight Demo With Shadow And Normal

Here is a demo of a few of the shaders I have created to emulate a flashlight.
These shaders use a projected texture I made and have a few quality levels
for slower machines.

You toggle the normal mapping support on and off with key 1
You toggle the shadow mapping from the flashlight on and off with key 2
You toggle the film grain effect on/off with key 3 (off default)



I made some shaders that are identical, but use per pixel spotlight cones
instead of projection, they are faster, but not as nice as this method.

This is just a small room with a couple of normal mapped models in it.
The intention is to demonstrate the shaders, I know the environment
stinks! So you are not really missing much if you dont download the ~34 meg demo.

These shaders are still a work in progress as part of a larger work.
I never thought I would be able to do this stuff with Gamestudio, but lately
the engine is really changing!

Thanks for looking!

File Front Download

I have yet to try it, but the screenshots look promising!

Perfect!

But performance is slowly.
(My pc system: 3ghz Hyper-Threading,1gb ram,radeon 9800 pro) fps is "23-24".

do you plan on sharing the code with us?
currently im downloading the package, but 34 sounds a bit large :O
is this A6 or A7 by the way? the screens look great so far ^_^ great job.




Ok, so i tested it now... WOW looking really great man!
i really hope you wanna share the shadowmap shader
looks awesome! can you tell a bit more about how you did it and all?
cuz i keep reading shadow shaders are so hard to do etc etc and ehre you go create a real nice one together with a projection shader! :O
does the porjection allow for multiple projectors per level? that'd be awesome...
anyway, keep it up!

regards,

Emre:
That concerns me some, I havent tested it on other machines. My machine is
same as yours but I have 512 more ram with a nvidia GeForce 7800 GS, and I get
~93 fps (900x600) with all effects turned on. You need vs1.1 and ps2.0 for all
shaders. I wonder what others are getting?

I'll make you a deal, If you give away your ragdoll system, I'll give away my
(this) flashlight system/shaders! Deal?
BTW, Its all done in A7 Lite-C.
Thanks for the comments man!

The normalmapping looks great
The shadows should be a bit darker and what I miss are soft edges
Because the lightview is always near to the camera and facing away from it, you
don´t have to care about antialiasing and are using just some basic
shadowmappingcode right?
How do you handle the normalmapping together with the projectionshader? Dou you
just place a pointlight at the lightsource and multiplicate the result with the
projected texture?
And than you just combine it with the shadowmapping, don´t you?
I am just interested because I thought about something like that just a few days
ago

the shots look great, but can someone please upload it to a different host, like file front?

YOU GOT YOURSELF A SWEET FRIGGIN NICE DEAL!
gheheheheheee, honestly, i was gonna upload it anyway, just had nearly _NO_ time on other projects besides the one im currently involved with. (and killzone, lol)
i'll build in basic stuff to not update every frame, and maybe even a way to turn the whole system for each ragdoll individually off... that would be really nice i reckon :/

i guess i can have it done by the weekend i'll let ya know

and btw, does it support multiple projectors ?
