Great. Thanks for sharing.

[djes]

Yeah, what a nice example
Nicer :

Code: Select all

CreatePlane(1,1000,1000,256,128,1,1)

[Fred]

Excellent !

[flood]

Thanks for this. I figured out how to add more parameters, like changing the color etc, but do you know if there is a way to change the transparency? Also, is it possible to send a string to a .material script?

Thanks!

[bobobo]

excellent only when you don't have a onboard Intel 965 Express

I see a gray plane and no ocean.

that is indeed better than the water.pb in examples.
in opengl-mode this will hang at RenderWorld()

but in "normal" mode this runs ok including those nice underwater-rays

Thanks guys!

Thanks!

flood, I haven't really looked into it. I was just interested in getting shader parameters working.
Not sure how you'd do transparency and I don't think you can send strings to a material script.
if you want to look into shaders in more detail get a copy of the ogre sdk and look at it's material scripts
and check out lighthouse3d.com the glsl tutorials and examples.

here is the idle ocean inside a teacup, thanks DK_PETER for the update to pb5.31.
the cylinder instead of a plane is like this:
CreateCylinder(1,10,0)
CreateEntity(1,MeshID(1), #PB_Material_None )
ScaleEntity(1,1,1,0)
so its Lenght=0 and scaled on z to 0 , if not scaled to 0 we will see like tides on the suface. also change WaveFreq and others to other values (just experimental).
also try the surface as sphere. i get a pure liquid ball if we use:
CreateSphere(1,10)
;CreateCylinder(1,10,0) ; ;create a surface to render the tea liquid on
CreateEntity(1,MeshID(1), #PB_Material_None, 0,100,0 )
ScaleEntity(1,1,1,0)
unexpected really, the thin sphere body with z scaled to 0 will be 100 units in the sky but (say the sphere soul) will stay spherical inside the teacup
seems to me the wave mathematics in file Ocean2GLSL.vert are advanced and using calculus so there is a possibility to use these equation in the normal waving flag mesh, but the the cpu will not work good like in this shader which use i think the gpu !!!

use the DK_PETER Screen3DRequester.pb updated file above with the idle ocean zip at the top of the page.
the following file is the ocean.pb updated by DK_PETER , but changing the surface to cylinder, and disabling the space key. compile With OpenGL subsystem

Nice! Only problem is the cylinder..If it isn't flat, you'll be able to see artifacts from the cylinder itself...(bug already reported some time ago).

I've take idle's project further even though I wrote, that I wouldn't.

Here's the new Idle's watershader project. Completely PB 5.31 compatible.

EDIT: You still switch ocean material using keys 1 and 2.
