OPENCASCADE 6.5.3 FREE DOWNLOAD

Precautions Back-up your code before the upgrade. In case of a closed wire, the inner region will always be inside the wire at that, the edges orientation is not taken into account. Thus the geometry is usually understood as a mathematical description of a shape, e. The following auxiliary definition have been removed as well: BitBlt , this will not work anymore. For input shape of another type the method always returns empty list. It seems that currently this part of the library develops most rapidly.

Opencadcade the set of used topological primitives changes from one kernel to another, while such objects as faces, edges and vertices are always present exactly these objects get connected with geometric primitives, while all others play a purely structural role.

The same changes use of adaptors instead of direct call to curve and surface methods should be implemented in relevant places in the applications based on OCCT to get the maximum performance. OCCT geometry is defined in a standard parametric form. Therefore keeping one selection mode as object field makes no sense.

The opencascave auxiliary definition have been removed as well: Blocksand Building with Xcode. About trends It is well understood that the functions related to geometric modeling should be as reliable as possible. If you get compiler errors or warnings when trying to build the upgraded code, you will need to fix them manually.

Open CASCADE Technology Overview

Methods ModeConsiderLo and Apply with three arguments have been removed. The previous approach with dedicated aspects per primitive type was handy in simplified case, but lead to confusion otherwise. You can read more about the company history on the official company web-site.

Presentation tools for building Wireframe presentation have been refactored to eliminate duplicated code and interfaces. Discret theShape, theDeflection, theAngularToler. SetGroupPrimitivesAspect should be the main method defining presentation attributes. This is done to prevent possible unintended errors like this:.

The code example below demonstrates opencascaxe to read shapes from a storage driver using StdStorage class.

Keep in mind the following:. This document provides technical details on changes made in particular versions of OCCT. Revise application-specific custom presentations to provide a proper bounding box, otherwise the object might become erroneously clipped by automatic ZFit or frustum culling algorithms enabled by default.

While immediate viewer updates are useful for beginners the result is displayed as soon as possiblethis approach is opencwscade for batch viewer updates, and having default value as TRUE leaded to non-intended accidential updates which are difficult to find.

The Relocation table now keeps HeaderData of the document and a format version can be extracted in the following way: A precise BRep-model is "better" than a discrete one to the effect that it can always be converted into both, voxels and 3D meshes of kpencascade quality. This architectural redesign may require appropriate changes at application level in case if custom Interactive Objects are used.

Most of typical changes required for upgrading code for OCCT 7. The full list of errors and warnings, with associated data such as problematic sub-shapes, can be obtained by method GetReport. HilightAttributes and process it in the entity owner. Visit our sister sites: Thus it may be necessary to include header of the corresponding class to make the code compilable. The applications that need to scale such objects depending on viewport size should update them manually.

List and map classes in NCollection package now require that their items be copy-constructible, but do not require items to have default constructor. Company has been making great efforts to promote its OCCT kernel over the last opwncascade. Another possibility consists in defining additional template variant of the overloaded function causing ambiguity, and using SFINAE to resolve the ambiguity.

Draw command vcolorscale now requires the name of ColorScale object as argument.

Open CASCADE Technology: Upgrade from older OCCT versions

Note that this method takes additional argument indicating the gravity of the message Trace, Info, Warning, Alarm, or Fail. The algorithm creates the different copy of this edge for each face.

This automatically enabled the possibility to use the handle to a derived class in all contexts where the handle to a base class was needed, e.
