Compare DreamFusion vs. Playbook

Recent advancements in the realm of text-to-image synthesis have emerged from diffusion models that have been trained on vast amounts of image-text pairs. To successfully transition this methodology to 3D synthesis, it would necessitate extensive datasets of labeled 3D assets alongside effective architectures for denoising 3D information, both of which are currently lacking. In this study, we address these challenges by leveraging a pre-existing 2D text-to-image diffusion model to achieve text-to-3D synthesis. We propose a novel loss function grounded in probability density distillation that allows a 2D diffusion model to serve as a guiding principle for the optimization of a parametric image generator. By implementing this loss in a DeepDream-inspired approach, we refine a randomly initialized 3D model, specifically a Neural Radiance Field (NeRF), through gradient descent to ensure its 2D renderings from various angles exhibit a minimized loss. Consequently, the 3D representation generated from the specified text can be observed from multiple perspectives, illuminated with various lighting conditions, or seamlessly integrated into diverse 3D settings. This innovative method opens new avenues for the application of 3D modeling in creative and commercial fields.

Our API facilitates the streaming of 3D scene information into ComfyUI diffusion-driven workflows. It is made available through our web editor, which empowers users to guide image generation using 3D elements. The platform accommodates custom workflows and LoRAs, catering to teams and enterprises that are integrating AI into their production processes. At Playbook, we are committed to the idea that AI can significantly enhance the quality of work, and achieving this requires seamless integration between the model, application, and final product. Users retain ownership of the assets generated through our platform, provided that the inputs used do not infringe on the copyrights of others. As spatial computing (AR/VR) continues to gain traction, along with the growing demand for visual effects (VFX), the necessity for an efficient 3D production pipeline that can deliver real-time content at an accelerated pace becomes increasingly evident. Playbookengine.com serves as a diffusion-based rendering engine designed to expedite the journey from concept to final image using AI technology. Accessible through both a web editor and an API, it also supports scene segmentation and re-lighting features, enhancing the creative possibilities for users.
