Re: [osg-users] dynamic cube map

Hi, I got the depth data from reflected objects. I needed to render the depth buffer to texture. Follows my update code: C++ code: Code: // OSG includes #include #include #include #include #include #include #include #include #include #include #include #include // C++ includes #inc

Re: [osg-users] dynamic cube map

Hi Nick, I still need help to get the normal/depth data from reflected objects. Could you have a look in my current code? C++ code: Code: // OSG includes #include #include #include #include #include #include #include #include #include #include #include #include // C++ includes #in

Re: [osg-users] dynamic cube map

Hi Romulo, more proper example is osgprerendercubemap - how to setup the RTT for cubemaps. Then you can have a look again in the OpenIG project, in the Triton plugin, line 70 - 114, that is the shader to generate HeighMap, for your case instead of the world Z you put in the output Z from the camer

Re: [osg-users] dynamic cube map

Hi Romulo, I guess you should do a render to texture and make sure the texture format is with texels as floating points. Then custom shaders that will render normals and depths into these textures. I am on travel at the moment will help you more when I get back. Meanwhile you can do research. Sta

Re: [osg-users] dynamic cube map

Hi Romulo, if the normal and the depth are encoded in the env texture I believe the answer is yes. Are you encoding the normal and the depth into texture? if so, can you provide snippet? On Sun, Dec 10, 2017 at 6:38 AM, Rômulo Cerqueira < romulogcerque...@gmail.com> wrote: > Hi Nick, > > I have

Re: [osg-users] dynamic cube map

Hi Nick, I have a deep look in your code and I have a doubt. The cube mapping results provides the reflected color. Is it possible to get the normal and depth instead of the reflected color? Best regards, ... Thank you! Cheers, Rômulo -- Read this topic online here: http://

Re: [osg-users] dynamic cube map

Hi Romulo, have a look at the OpenIG project sources, it has it implemented with GLSL https://github.com/CCSI-CSSI/MuseOpenIG/blob/master/Plugin-ModelComposition/IGPluginModelComposition.cpp Look here for "environmental", starting from line 395. Here you use texture cache to set up the 6 textures

Hi Rômulo, Have a look at the osgprerendercubemap example as it illustrates how to set up multi-pass rendering to render to the six faces of the cubemap. Robert On 5 December 2017 at 01:26, Rômulo Cerqueira wrote: > Hi, > > I would like to use the dynamic cubemaps to reproduce the mirror effect

Re: [osg-users] dynamic cube map

maybe you dont need cube map for what you want to achieve. Have you seen the osgreflect example ? Does it works for you ? -Nick On Wed, Feb 10, 2010 at 1:42 PM, Sebastien Nerig wrote: > Hi Nick, > > Well the changes are minors. I just wanted to change de reflector from the > sphere to the bottom

Re: [osg-users] dynamic cube map

Hi Nick, Well the changes are minors. I just wanted to change de reflector from the sphere to the bottom plane (or box). here is my reflector function, I changed the sphere to a box geode, ie the bottom plane/box. Code: osg::NodePathcreateReflector() { osg::PositionAttitudeTransform*

Hi Nick, ok I did have a look at the osgPrerenderCubeMap code and at you thread about mixing a static 2D texture and a dynamic cube map into a shader. btw your version with Code: { osg::Uniform* u = new osg::Uniform(osg::Uniform::SAMPLER_CUBE,"cubeMapUnit"); u->set(unit); node->getOrCreate
