Frame Cache

The component caches decoded frame data in memory for smooth playback. Configure the cache with:

// Limit cache to 512 MB
model->setCacheMemoryLimit(512 * 1024 * 1024);

// Query the configured limit
size_t limit = model->cacheMemoryLimit();

// Pre-load the next 10 frames for smooth animation
model->preloadFrames(model->currentFrameIndex() + 1, 10);

// Query current cache usage
size_t usedBytes = model->cacheCurrentMemoryBytes();

The same cache API is available at the reader level via ParticleDatasetReader::setCacheMemoryLimit() and ParticleDatasetReader::preloadFrames().

To explicitly discard all cached frames (e.g. when switching scalar fields at the reader level):

reader.clearCache();
