Re: [osg-users] [osgPPU] osgPPU for image processing

Dear Mr. Art Tevs, I have been able to sort out the problem I posed yesterday, i.e., making the texture Image available for analysis / parameter determination. Similar to your osgPPU::UnitOutCapture, a class called UnitTextureTap is derived from osgPPU::UnitOut. It overrides the

Hi all, I think that it can be a good thing to tell you I just found a crash in the Writer in the plugin IVE. The crash occurs when a drawElementUInt is empty. osg::ref_ptrosg::DrawElementsUInt drawelems = new osg::DrawElementsUInt(GL_TRIANGLES);

Re: [osg-users] osgconv IVE to OSG create DDS?

Hi Chris, The ImageLayer is part of osgTerrain, and just wraps up an osg::Image with geospatial coords to place it in the correct place on the terrain. At runtime osgTerrain actually creates an osg::Texture2D for each ImageLayer, but this is not something that is saved to disk, as the ImageLayer

Hi, I saw the Update function and understood that you're absolutely right! I saw more accurate results also! Yesterday I changed the function to retrieve the normal too. Now with the normal I can make the models not only to move up and down but rotate also when a wave passes. I will try to use

Re: [osg-users] Crash in ive writer

Hi Vincent, I just checked the src/osgPlugins/ive/DrawElements*.cpp files and none of them check for an empty array before attempting to write out the array. I'm surprised it crashes as I would have thought trying to write out 0 bytes from an array wouldn't require any pointers to be

Re: [osg-users] [3rdparty] osgOcean collision detection

Hi Dimitrios, The interpolation function in OceanTile works on indices fetching the vertices from the vertex array within it. So you pass it the 4 unique row/column indices that make up the surrounding four points and then a row and a column index for the target point (tx ty). For your

[osg-users] [osgPlugins] OBJ plugin loader places model at wrong position and with wrong attitude

Hi, I am using the obj plugin to load polygonal models, but it seems that the models are placed at wrong positions and with a wrong attitude in the coordinate system. I have a model that is centered at (1014, 1025, 999), but it is placed at coordinates (1014, -999, 1025). In the program we

I found the problem. The complex app was creating it's own root node and setting it's rendering hint to transparency. Not sure why it did that. Now it's working like a charm. Thanks, Brian -- Read this topic online here:

Hi Harash, Subsampling/Resampling: Yes, the UnitInResampleOut, do resample the input texture to the size you want to have it. However it use the default hardware resampling algorithm, so GL_LINEAR. From your question, I thought you are thinking of some lagorithm wich do something better than

Hi, Guys Just wanted to followup. And thanks Roger for the sample code. I ended up making it work while we build the scene graph rather than doing it after in a traversal. Thanks again. BTY, Safe is hiring software engineers with Google Earth and General GIS and 3d experience.

Re: [osg-users] Rendering Optimizations Not Working

Hi Robert, My comment Not sure why it did that was about why the complex app wanted to set the transparency, not why it changed the performance. Once I found it I understood what it was doing - render order based on distance from camera instead of order based on optimized state. BTW - kudos

Hello Michael, With the sobel filter I get ~360 fps. With the 5x5 Gaussian blur I get ~300 fps. The graphics hardware is a GeForce GTX 280. Just curious, to put that into perspective, what frame rate do you get without filtering on the same scene? (just so we can get an idea of the

Re: [osg-users] [osgCompute] PostProcessGL

Sure, after removing the filter I was getting ~530 fps. Since fps is nonlinearly related to frame time, here's the breakdown: 530fps = ~1.89ms 360fps = ~2.78ms (sobel) 300fps = ~3.33ms (5x5 guass) So the cost of applying the slightly more expensive 5x5 filter kernel cost about 3.33ms -

Hi Michael, Sure, after removing the filter I was getting ~530 fps. Since fps is nonlinearly related to frame time, here's the breakdown: Thanks for the breakdown. Since the filtering is a post-process operation it's basically a fixed cost per frame... 1.44ms is not bad. J-S --
