HDR , DOF and Skybox

[Icare]

Hi,

 

Yes, me again , I'm looking at every feature of my new 3D engine

 

But Like my other post, may be a bug or not :

 

HDR => OK

DOF => OK Only if I create a new camera, I don't use the camera who come from the framework

HDR + DOF => OK Only if I create a new camera, I don't use the camera who come from the framework

skybox only => OK Only if I use the camera who come from FrameWork

HDR + skybox => not ok, I don't see the HDR

HDR + DOF + skybox => not ok, because I must use a new camera to see the DOF and with a new camera I don't see the skybox

 

If someone have a complete exemple it will be good

 

My scene with out HDR

 

HDR set to TRUE

 

HDR set to TRUE + Skybox => :-( non HDR

 

 

DOF set to TRUE + Skybox with a new camera => I dont't see my sky

 

DOF set to TRUE + Skybox with framework camera=> I dont't the DOF

i think you may have hit upon somethinbg here... i'm getting similar results...

 

in 2.26 i can see dof effects with the default fw renderer and cam with the following code...

fw.renderer.SetFarDOF 1
fw.renderer.SetNearDOFStrength 1	
fw.renderer.SetFarDOFRange Vec2(0,50)

 

the same code doesn't seem to work with 2.31 or higher...

 

no crashing... just no DOF effects...

 

 

btw... the brick and the moss and brick filling textures come across verrrry nicely...

Thank but The textures aren'tmine, but come from Filax of Blitz3Dfr

 

I am testing in the editor, and it's even more strange, I have the DOF and the skybox, but no HDR ...

DOF used to be an issue in 2.31 and was listed in the bug tracker. It has been fixed and works now in 2.32.

 

EDIT: When you say no HDR, what are you meaning? Perhaps the HDR that you are expecting may be the problem. HDR in LE is a subtle effect that really is only noticeable when you have contrasting bright and darkened areas. The only time that I ever really notice a difference with HDR is when I have bloom on. Also, you need to add your computer spec's to your signature.

I don't say it doesn't work, I say I can't make a skybox and DOF work with the Framework.

It's either one or the other, look at my screen capture.

 

Ditto for the HDR, if there is a skybox that doesn't work anymore, if I remove the skybox there is a visible difference between HDR and not HDR ... look at my screen capture

 

May be, there is a little bug with the framework, or can you post a complete exemple of DOF + SKYBOX in blitzmax made with the framework

there's no bug that i can see... here is an example that allows you to set AA, bloom, godrays, ssao, hdr, wireframe, and dof.

 

you also need the lua-gluefunctions.bmx to be able to incorporate the lua objects (environment_atmosphere, lights, etc..) from the sbx scene.

 

 

and this is just a small example that sets the skybox and DOF:

Framework leadwerks.engine
Import "c:\program files\leadwerks engine sdk\bmx\framework\framework.bmx"
GCSetMode(2)
AppTitle:String = "SkyBox and DOF"
RegisterAbstractPath ("c:\program files\leadwerks engine sdk")
Graphics(800, 600)

Global fw:TFramework = CreateFramework()
If Not fw RuntimeError "Failed to initialize engine."

PositionEntity(fw.Main.camera, Vec3(.5, 0, - 2), 1)

SetSkyBox(LoadMaterial("abstract::FullskiesBlueClear0016_2_L.mat"))
SetBackgroundColor(Vec4(1, 1, 1, 1))
SetFarDOF(1)
SetFarDOFStrength(1)
SetFarDOFRange(1.5, 5)

Global light:TLight = CreateDirectionalLight()
RotateEntity(light, Vec3(45, 45, 0))

Global mat:TMaterial = LoadMaterial("abstract::cobblestones.mat")
Global cube1:TMesh = CreateCube()
PaintEntity(cube1, mat)

Global cube2:TMesh = CreateCube()
PaintEntity(cube2, mat)
PositionEntity(cube2, Vec3(1.5, .5, 2), 1)

HideMouse()
fw.SetStats(1)
Repeat
If KeyHit(KEY_ESCAPE) Exit
       If AppTerminate() Exit

TurnEntity(cube1, Vec3(.15, .15, 0))
TurnEntity(cube2, Vec3(-.15, 0, -.15))

fw.Update()
fw.Render()

Flip(0)
Forever
fw.renderer.gbuffer = Null
GCCollect()
ShowMouse()
End

Thank a lot macklebee, every thing is working now !

 

I can explain why I have some bug in my test, I set a setting like this SetFarDOFRange(200,500) (too large to be seen with my scene), I created a new camera and I saw my DOF.

 

Necessarily when I have my skybox, I used the camera of the framework (which is normal), but the range of DOF was too large to be seen.

 

Now we know that with a camera set up in parallel to those of the framework we see the DOF even if it is out of range.

glad to hear it.

 

for future reference, look at the framework examples in the wiki
