.drf File Extension

Developer: Autodesk
File type: VIZ Render File
You're here because you have a file that has a file extension ending in .drf. Files with the file extension .drf can only be launched by certain applications. It's possible that .drf files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .drf file?

The VIZ render files are digital 3D images saved in the DRF format. The "DRF" in this file format stands for Discreet Render Format, and these DRF files are affixed with the .drf extension. The Autodesk Architecture software, particularly older versions of this program, is bundled with the VIZ Render application, and this program is used to create, open and edit the content of files in the DRF format. The content of a DRF file usually consists of rendered images that make up building designs among other modeled architectural designs of various structures developed and entered by the authors of the DRF files. The 3ds Max 2013 software can be used to open and view the content of these DRF files. There are versions of this application for Mac and Microsoft Windows-based systems. Users can only open and view the content of these DRF files with the Autodesk 3ds Max 2013 software (also developed by Autodesk), since this application is not implemented with support for saving projects in the DRF format, though users can export these DRF files into MAX projects, which are saved in the MAX format and appended with the .max extension.

how to open a .drf file?

Launch a .drf file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .drf file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .drf files aren't yet associated with it. In this case, when you try to open a .drf file, you can tell Windows which application is the correct one for that file. From then on, opening a  .drf file will open the correct application.

Autodesk 3ds Max 2013 for Mac

Autodesk 3ds Max 2013 for Mac

In installing Autodesk 3ds Max 2013 for Mac, the user's system must use Boot Camp or Parallels Desktop 4.0 so that it can manage an OS with a dual configuration to meet the minimum system requirements. The Boot Camp is a utility that helps in enabling Mac OS to operate on a dual boot system. Parallel desktop is also a system utility developed by Parallels Inc. that uses a guest operating system to map the resources of the computer host's hardware into a a virtual machine. Mac users must have enough memory so that the Mac OS X and Mac application together with the memory needed for the virtual machine's operating system in order for it to run smoothly. Mac users also has the option of Virtualization which allows Windows operating system to run as a guest within the host which is the Apple Mac OS. The hardware requirements for Mac are as follows, and Apple Mac OS X 10.5.x or higher operating system, Processor should be Intel based Mac with 64-bit Windows Vista requires an Intel Core 2 duo or Intel Xeon processor. Minimum requirement for RAM is 2 GB but the recommended are d 4-GB for 32-bit guest OS, 8-GB or more for 64-bit guest OS. disk space should have a minimum of 20-GB for the Apple OS partition, minimum 20-GB for the guest OS partition and the Boot Camp version should be V 2.0 or higher.
Autodesk 3ds Max 2013 with SpeedTreeMAX plugin

Autodesk 3ds Max 2013 with SpeedTreeMAX plugin

SpeedTreeMAX plugin is integrated with the Autodesk 3ds Max 2013. SpeedTree allows users to add and place billboard trees into their designs as added scenery. It has 30 trees that are contained within a SPT File. SPT files has all the detailed information about the tree. There are also a variety of shrubs, both the trees and the shrubs comes with different levels of detail. Users can choose an SPT file by browsing on the SpeedTree Library folder. SPT files have suffixes like _LD, _MD, or _HD, which indicates their level of detail. _LD stands for Low Detail, _MD stands for Medium Detail, and _HD stands for High Detail. Once imported into the design, the tree quickly updates and even does re-computing, which happens in real-time, this will determine if the overall tree structure is suitable for the scenery. The user will be ready to render when the tree has been selected and its general shape established. In the plugin, the number of standard tree faces available for high detail is 100,000 and there are several options available for the low detail tree faces. It also comes with a built-in wind from 3ds max for realistic movements of tree which can even control individual leaf movement. SpeedTreeMAX plugin supports network rendering, users would only have to copy the plugin files to each system of the design and share it in a common location.

Autodesk 3ds Max or 3D Studio

Autodesk 3ds Max or 3D Studio

Autodesk 3ds Max was used to be known as 3D studio Max. It was a computer graphics model used in making 3D animation models and images and was used on a Microsoft Windows platform. Designers who used this software were mostly movie effects specialists, video game developers, architecture visualization studios, and commercial studios. It had features like MAXScript, Character Studio, Scene Explorer, DWG Import, Texture assignment and editing, General reframing, Constrained animation, Skinning, Skeletons and inverse kinematics, Integrated Cloth Server and Integration with Autodesk Vault. Originally, 3D Studio was running on a DOS platform. It was developed by the Yost Group and was published by Autodesk. On the 4th release of 3D studio in DOS platform, it was renamed into "3D Studio MAX" and was written for the Windows NT platform. This version was also created by the Yost Group and was released by Autodesk's media and entertainment division, the Kinetix. On the second release of 3D Studio Max, Autodesk purchased the product and developed it internally for the next two releases. The product name was later changed to "3ds max" and on its 8th release, the product was branded with the company logo of Autodesk. In the 2009 release of the product, its names was changed into "Autodesk 3ds Max".
Autodesk 3ds Max 2013

Autodesk 3ds Max 2013

Autodesk 3ds Max 2013 is a software that has specialized toolsets for gamedevelopers motion and visual effects artists. One of its tools is the 3D modeling, where users can create parametric and organic objects, with a Graphire modeling toolset that has 100 advanced polygonal modeling and freeform 3D design tools. It features Shading and texturing with a wide collection of mapping, texture painting and layering options. users can perform creative texture mapping like decal placement and spline mapping, they can also edit complex shading hierarchies, and use Viewport Canvas toolset to paint multiple layers in any maps. It features an animation that helps make believable, life-like characters. It has skit modifier and CAT muscle, 3ds Max bones inverse kinematics solvers and rigging tools that are customizable. By using its high performance toolsets, users can create dynamics effects and simulation. Through 3D rendering, users can achieve optimum image quality that gives predictable, photorealistic results. The Data transfer and Pipeline Integration enables users to import data from several sources, and also transfer 3ds Max and 3dsMax design data to users, locations, file iterations and software applications. This software also encourages Collaborative Workflows in which users can share date in complex scenes and lets others contribute to the task.

a word of warning

Be careful not to rename the extension on .drf files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .drf. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
