Point Light Problem

[MrIslomaniac]

Got a little problem here guys. I see the edge of an invisible cube through the shadows of my model, any clues?

#include "engine.h"

int main(int argc, char** argv)
{
Initialize();

//Create a graphics context
Graphics(800,600);	

//Create a world
if (!CreateWorld()) {
	MessageBoxA(0,"Error","Failed to create world.",0);
	goto exitapp;
}
CreateFramework();

//Create a camera
TEntity cam=CreateCamera();
CameraClearColor(cam,Vec4(0,0,1,1));
PositionEntity(cam,Vec3(0,2,-10));

//Create a light
TEntity Map = LoadScene("abstract::TestSystem.sbx");
TLight miau = CreatePointLight(100,0);
PositionEntity(miau,Vec3(0,0,0));

//Create a render buffer
TBuffer buffer=CreateBuffer(800,600,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);
int move=0;
int strafe=0;
TVec3 camrotation=Vec3(0);
float mx=0;
float my=0;

//Main loop
while(!AppTerminate()) {

//Camera look
if (MouseDown(1)){
	HideMouse();
	mx=Curve(MouseX()-GraphicsWidth()/2,mx,6);
	my=Curve(MouseY()-GraphicsHeight()/2,my,6);
	MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);
	camrotation.X=camrotation.X+my/10.0;
	camrotation.Y=camrotation.Y-mx/10.0;
	RotateEntity(cam,camrotation);
}
else if (!MouseDown(1)){
	ShowMouse();
}
RotateEntity(cam,camrotation);

//Camera movement
move=KeyDown(KEY_W)-KeyDown(KEY_S);
strafe= KeyDown(KEY_D)-KeyDown(KEY_A);
MoveEntity(cam,Vec3(strafe/10.0,0,move/10.0));

UpdateFramework();
RenderFramework();
//Swap the front and back buffer
Flip(0);
}
exitapp:
return Terminate();
}

here are the files you need: http://rapidshare.com/files/355513076/Test.rar.html

Thank you =)

DL'd your files and used your above code, cant seem to see what it is you refer to can you post a screenshot, all I get is a white sphere ...

[MrIslomaniac]

thats exactly what should happen...

But fly around it and look at the shadow edges heres a picture:

[Marleys Ghost]

Nope I have flown all round it .. up down left right back forward ... can't get that to happen. I am using your code as is except for a RegisterAbstractPath to my SDK directory, and the model and sbx you supplied.

[MrIslomaniac]

Thank you for trying mg!

Maybe it is something with my graphics card... Nvidia gforce 9600 GT

can you or someone else try this? it's the compiled version:

[Marleys Ghost]

Would no have thought (in this case) it was as we seem to have the same card.

[macklebee]

i get the same thing with your example... but was unable to get it to occur in my own example scene... or on any thing I have used around point lights...

[MrIslomaniac]

hmm weird...

which version of the engine are you guys using? i am using 2.31

[Marleys Ghost]

have you sync'd lately as I can get the issue with your compiled .exe but if I change the DLL's ect to the ones I currently have from the latest sync it seems to fix it.

[macklebee]

2.31...

 

perhaps it has something to do with the new shadow casting options... i notice that you do not have the "castshadows" key in your sbx file...

 

EDIT- agree with MG. you appear to be using an old shaders.pak... i replaced your pak with my current one and i cannot get that shadow error

[MrIslomaniac]

My version is up to date...

Can you look at the dll filesize? are they different?

EDIT Yes that was it now it works for me too =)

Thank you guys so much =)

appreciate it

Your welcome glad that little mystery is solved for you

[MrIslomaniac]

When I change the pointlight line to this:

TLight miau = CreatePointLight(1000,0);

it happens again ...

I know that in the editor you can only set it to 100 but i need it to light for a distance of 15000000 LE units ...

Solar system ftw ^^

[Marleys Ghost]

15000000 LE units ?

[MrIslomaniac]

Well the distance between the sun and pluto is 5913520000 km.

I already divide every value by 4.000.000 and take the result for the engine in Units ...

So for pluto that would be 1.478.380 meters, since you can set the camera view range to 3.000.000 i thought that would work ...

[Marleys Ghost]

you are not going to manage to scale the solar system very well to LE units I dont think. You may well have to fake it along the way.

[MrIslomaniac]

I just did another calculation, i could make the scale much smaller but I don't know what would happen if i load an object that is 0.1137 meters and i zoom very close...

of cause i need to slow down the camera and say that it should not stop rendering whats in front of it ...

i'll try that later today, hopefully it will work =)

Thanks again

[Marleys Ghost]

No probs... good luck
