TRiP

A proof of concept for a hyperflexible realtime abstract visualization & animation tool.

TRiP allows to interactively create and control a 3d scene via command line, the keyboard and provides a programming interface to connect other input devices, like e.g. MIDI-devices.

TRiP decouples scene entities from transformations and provides means to attach/detach transformations, materials and entities interactively. Furthermore, materials and transformations can be influenced interactively with mathematical functions and timers, e.g. to fade in or fade out animations.

Unfortunately, I stopped working on TRiP in favor of other projects.

The project is not maintained anymore.

Screenshots

Screenshots taken from real time animations. The screenshots depict a morphing and moving object or objects, with animated colors. The scenes were created in real time using the builtin interpreter language.

Prerequisites

TRiP is based on OGRE 1.7 (https://www.ogre3d.org) and the Object Oriented Input System (OIS) (https://github.com/wgois/OIS). The project is written in Visual Studio 2010. I recommend to use CMake in future.

Adding New Input Sources

TODO

TODO

• set enabled for Clusters shall do something meaningful
• use more references
• Script Parser
• Get Stats
• MouseFrameListener
• change keyboard mapping
• release-elements for the functions
• build a dtor for TripVarManager
• refac KeyboardInputListener überarbeiten
• Background color
• cout fps
• cout stats
• Switch between meshes / Materials
• Camera controls: Switch between centric rotation and fps-mode
• Recompile shader programs
• jump camera to selected entity
• think about Backstring System
• Keep ERRORPRONE in mind
• use external keyboard interpreter framework, something that supports inputl abbreviations like vim does with vimscript
• fill README.md

Geometry batching

//Load a mesh to read data from.
        InstancedGeometry* batch = mSceneMgr->createInstancedGeometry(meshes[mSelectedMesh] + "s" );
        batch->setCastShadows(true);

        batch->setBatchInstanceDimensions (Vector3(1000000, 1000000, 1000000));
        const size_t batchSize = (mNumMeshes > maxObjectsPerBatch) ? maxObjectsPerBatch :mNumMeshes;
        setupInstancedMaterialToEntity(ent);
        for(size_t i = 0; i < batchSize ; i++)
        {
            batch->addEntity(ent, Vector3::ZERO);
        }
        batch->setOrigin(Vector3::ZERO);

        batch->build();
// END Geometry Batching

get names of compositors

// gets the names of all compositors
auto iteral = Ogre::CompositorManager::getSingleton().getResourceIterator();
    for( auto it = iteral.begin();
        it != iteral.end(); it++)
    {
        std::cout << it->first << "\t" << it->second->getName() << std::endl;
    }
