Learn Open Cascade for Custom 3D App Development

Explore the OCC foundation classes I, the base module with the internal toolkit and the math toolkit, the two main toolkits, providing dynamic memory management, collections, and geometric modeling.

Explore OCC foundation classes and the GP package to create 2D and 3D analytical geometry—points, vectors, lines, planes, circles, ellipses, hyperbolas—along with translations, rotations, and scaling.

Create a 3D viewer in an MFC application using Visual Studio by initializing an OpenGL context, setting lights and camera, and applying an orthographic projection for the view.

Extend the overview class with Windows message handling for mouse input, define gesture-based pan, zoom, and rotate controls, and build menus to switch camera views in the viewer.

Explore the modeling data module in Open Cascade to create 2D and 3D geometry with the G2 engine toolkit, covering 2D classes like points, lines, circles, ellipses and 3D concepts.

Explore three-dimensional geometric modeling with the GTD toolkit, creating points, lines, planes, and surfaces, and building 3d sketches into complete models.

Learn how to create 3D features with extrude and revolve, defining sketches, faces, thickness, and 360-degree revolutions to build solid bodies, and control material addition or removal using fuse.

Learn 3d modeling in open cascade by building solids from open profiles, applying offsets, and performing sweep and loft along paths, with 2d sketches to 3d cross-sections.

Learn to create fillets and chamfers on 3d model faces using edges and vertices, and apply template features with a topology explorer to modify the surface.

Master surface modeling with GM API classes to create cylindrical, extruded, and offset surfaces. Learn to convert objects between GM and spinco representations and build solid bodies from profiles.

Explore advanced surface modeling in Open Cascade by composing sweeps, passing through sections, and using section generators and boundary curves to create, stitch, and refine surfaces.

Create axis aligned and oriented bounding boxes for 3d topology objects using two functions that decompose shapes and update the bounding box with inertia and center of gravity.

Explore how to display 3D objects with Open Cascade, control display properties such as color, edges, and dash or dot styles, and convert topology into graphics objects for interactive viewing.

Learn to display datum objects in a 3d viewer using Open Cascade, including axis objects, planes as triangles or rectangles, and setting color, length, and display mode.

Clip 3d objects with planes, cap the surfaces, and apply textures or colors to caps. Generate cross-sections and compute properties like area from clipped shapes.

Create a custom interactive object in Open Cascade for 3D app development by converting surface geometry into a displayable object and implementing compute and selection for shaded and wireframe modes.

Create a custom interactive 3D object by building a mesh from nodes and elements, convert quadrilaterals to triangles, and visualize it using Open Cascade's visualization framework.

Explore the application framework for CC, examining its inbuilt data management system, data tree of attributes, labels, and documents, and use the LCF toolkit to drive topology-aware modeling algorithms.

Explore how visualization attributes drive the display of topology objects as shapes within the Open Cascade framework, linking labels, the name ship attribute, and presentation attributes to interactive view updates.

Learn to implement the OCC document template in MFC, defining document and view classes and handling create, open, save, and view operations within the document framework.

Create a parametric multi-part 3d model using Open Cascade by defining cone and cylinder parts, setting dimensions and labels, and assembling them into a final model with automated workflows.

Learn to import and export 3d models using standard data exchange formats like step and iges, converting reader data into shape objects and generating triangulation for viewer display.
