Re: [osg-users] cannot load PNG image
Hi Tufan, Check also that C:\Users\Tufan\Desktop\New Folder\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2 directory is in your path. If directory is in your path, attach your texture and code. I will try it. Selman On Thu, Jan 7, 2010 at 1:47 PM, Tufan Taş tas.tu...@gmail.com wrote: Hi, Yes C:\Users\Tufan\Desktop\New Folder\OpenSceneGraph-2.8.2\bin is in my path.

[osg-users] Projective Texture Mapping
Hi everyone,
I've tried osgspotlight example and it works fine. I've generated
*only*seven texture coordinates by using osg::TexGen and rendered the
spotlight
effects by fragment shader. But, I want to render multiple spotlight effects
in my scene (for example 20 spotlight effects).
*
void main(void)
{
vec4 sceneColor = texture2D(baseTexture,gl_TexCoord[0].xy);
vec4 spotColor1 = texture2DProj(spotTexture1, gl_TexCoord[1]);
vec4 spotColor2 = texture2DProj(spotTexture2, gl_TexCoord[2]);
vec4 spotColor3 = texture2DProj(spotTexture3, gl_TexCoord[3]);
vec4 spotColor4 = texture2DProj(spotTexture4, gl_TexCoord[4]);
vec4 spotColor5 = texture2DProj(spotTexture5, gl_TexCoord[5]);
vec4 spotColor6 = texture2DProj(spotTexture6, gl_TexCoord[6]);
vec4 spotColor7 = texture2DProj(spotTexture7, gl_TexCoord[7]);
vec3 spotColor = spotColor1.rgb + spotColor2.rgb + spotColor3.rgb +
spotColor4.rgb + spotColor5.rgb + spotColor6.rgb + spotColor7.rgb;
vec4 color = sceneColor * gl_LightSource[0].ambient;
float spotMapIntensity = 1 - gl_LightSource[0].diffuse.g / 3;
gl_FragColor = vec4(sceneColor.rgb * spotColor.rgb, 1.0) *
spotMapIntensity + color;
}*
Is there any suggestion about this subject? How about *deferred lighting*method?
Thanks.
Selman

Re: [osg-users] rendering ive model (shaders)
Hi Ümit, Actually, I want to know solutions of two combinations. Firstly, if textures are seperated from models, how can I pass the texture in uniform variables? I have lots of models and I don't know whole information about textures (name, location vs.). Can I get information about model textures from ive model? Thanks Ümit.

[osg-users] model opacity problem
Hi everyone, In our projects, we make lots of 3d models by using 3d Studio Max that has opacity map. And then, we convert these models from 3ds format to ive format by using ive exporter. But, when we integrate (osgDB::readNodeFile) these models in our osg and Qt application, the program crashes. If models has not opacity map, the program works. Anoyne experienced about this problem?

I haven't personally tried multiple osgParticle::PrecipitationEffect, when I wrote it I had in mind that only one would likely be active at any one time. Do you have multiple PrecipitationEffect active at one time? What effect are you trying for? If you have multiple effects on at one time then perhaps lazy state updating on the uniform might be causing problems. This is just a wild guess though.

[osg-users] Terrain Texturing
Hi everyone, I've implemented Terrain Rendering Using GPU-Based GeometryClipmaps algorithm with frustum culling, instancing, normal maps, procedural texturing etc... And now I want to implement texturing of terrain other than procedural texturing. Because I want to cover terrain area with unlimited texture data. A lot of texture data means a lot of alpha map. (Texture Splatting) and GLSL doesn't allow more 16 sampler2D. Can I cover terrain area with unlimited texture?

Re: [osg-users] Vertex Buffer Object (Multi Window)
Hi Robert, Thanks a lot for the quick response. I have solved this problem with your help. I do with this following call, Producer::RenderSurface::*shareAllGLContexts*(true); But, this time, when I create more than one VBO, float* cachedData = static_castfloat*(mExtension-glMapBuffer(GL_ARRAY_BUFFER_ARB,GL_READ_WRITE_ARB)); function always returns NULL and I can't map GPU buffer. But it works for one VBO for multiple window. On Sun, Mar 16, 2008 at 6:42 PM, Robert Osfield [EMAIL PROTECTED] wrote: Hi Selman, This is the way that OpenGL objects work - they aren't by default shared between separate graphics context. You'll either need to maintain separate VBO's for each context or share graphics contexts. There is a lot of support in the OSG for managing separate objects across multiple graphics contexts so is you use classes like osg::Geometry it'll manage this all for you. Robert.
