[osg-users] [build] Performant handling of lots of changing objects

Hi, first of all: I am new to OSG! I like to programm a diplay for scientific purposes. I want to display lots (lets say 500 - 10.000.000) Boxes. At each time cycle (100ms) ist can be 500 - 10.000.000 Boxes. All examples I read so far contained a allocation of memeory for all of those Boxes

Re: [osg-users] How to compute speed?

Hi Shiina, A way to do it could to add an update callback that get the world transform on the object each frame, then for the time you have the framstamp, or can get the time with osg::Timer::instance()-time_s() you can store position and time at previous frame, and do your computation like that:

Hi Michael, The test you have in hand is very nieche, handling 10 million elements will require special care in creating and managing the scene graph. To get decent performance you will have most likely have to batch the box primitives into groups, and using geometry instancing will probably be

Hi Martin, Now I change the values of _x and _y during the runtime, but the geometry isn't changing. I would like pass a pointer to the osg::Vec3 and use the function dirtyDisplayList. Well, maybe I don't understand something, but you can always get the vertices from the array and modify

Invalid value suggest OSG is passing an invalid parameter to a function such as glScissor. A couple suggestions: * Look at your code and determine how you are configuring the Stencil StateAttribute. * Set a breakpoint in Scissor::apply and ensure OSG is passing valid values to all OpenGL
