Castle Model Viewer vs T

Viewer for 3D and 2D model formats supported by the Castle Game Engine: - glTF - X3D - VRML - IFC - Spine JSON - sprite sheets (in Castle Game Engine, Cocos2D and Starling XML formats) - MD3 - Wavefront OBJ - 3DS - STL - Collada - and more. In addition to the above formats, it also allows to open a ZIP file that contains a single model and associated media (like textures, sounds etc.). You can change navigation type (walk, fly, examine, 2D), jump between viewpoints, play chosen animations, save a screenshot, display scene statistics (triangle, vertex count) and more. The application comes with a few sample files, and naturally you can open your own 3D and 2D model files. The models must be self-contained, e.g. you have to - use GLB with all the textures packed in one file, - or X3D with all textures expressed as PixelTexture or data URI, - or just put your model with data (like textures) inside a zip. - We have documented how to make your models self-contained here: https://castle-engine.io/castle-model-viewer-mobile This is an open-source software, available to you for free. There are no ads or tracking. We appreciate if you can support us: https://www.patreon.com/castleengine !

T-Sketch is an infinite canvas for sketching, drawing, and real-time collaboration. Think, plan, and create with your team on one shared canvas—whether you brainstorm on iPad or join from the web. DRAW FREELY • Infinite canvas — pan, zoom, and never run out of space. Your ideas can grow without limits. • Natural drawing — pens, brushes, and effects that respond to pressure and tilt. Use Apple Pencil for precise strokes. • Rich content — freehand strokes, lines and arrows, rich text, images, and searchable symbols on the same canvas. • Editable objects — move, resize, rotate, and recolor anything without redrawing. Iterate non-destructively. COLLABORATE IN REAL TIME • Work together — multiple people can draw and edit at the same time. See live cursors and changes as they happen. • Share by link — send a viewer or editor link so others can open the sketch in the app or in the browser. No account required for viewers. • Teams and projects — organize sketches in teams and projects. Control who has access. PRESENT AND EXPORT • Slides from your canvas — turn areas of your sketch into slides and present fullscreen. Sketch live during meetings or teaching. • Export — save as PNG images or export a full archive with all attachments for backup or sharing. MADE FOR CREATORS AND TEAMS • Cross-platform — use T-Sketch on iPad, on the web (Windows, Mac, Linux), or both. Same canvas, same collaboration. • Light and dark mode — the interface adapts to your canvas. Choose light, dark, or auto based on your background. • Optional Pro plan — free plan includes 1 project, 3 sketches, and 5 collaborators per sketch. Tronor Pro unlocks unlimited projects, sketches, and more collaborators. T-Sketch is built for visual thinking: brainstorming, system design, teaching, and creative exploration. Draw the way you think.
