This last step is carried out using the render controls located at the bottom of the animation panel:
The Render button is used to start the rendering. However, before clicking on the button, please consider the following:
To render an animation, you must name it, as explained in the Saving and deleting animations section. The name of the animation is also the name given to the resulting AVI file and the intermediate image files. This name will be given a suffix indicating the corresponding frame number. Thus, for a "Tour" animation consisting of 300 frames, the following files will be created:
Another essential step to render the animation is to select a destination folder where the intermediate image files and the final AVI file will be saved. To select the destination folder, click on the button with the folder icon. A dialog box will open where the user can explore the computer in search of the desired folder.
The rendering process can be time consuming and may require several hours or even days, especially if there are many frames to render, and/ or if the renderer selected is photorealistic and the image resolution is very high. Therefore, before starting the rendering, it may be convenient to set the render options in order to obtain the desired result and avoid having to repeat the process.
Selecting and Setting the Renderer
Lands allows to use two different renderers by default:
This is to use the same type of display that is used by AutoCAD for the views. The result is the same as in the animation playback, but saved in an AVI file so that it can be viewed outside the AutoCAD environment.
Another advantage compared to the playback is that the frames per second frequency specified in the animation will be ensured in the AVI file, because they do not have to be rendered and viewed in real time. However, it is not always possible in the playback, especially if a very high frame rate per second is specified and/ or if it is executed in computers that are not very fast and/ or the drawing files are very large.
When choosing this renderer, the resolution of the AVI file shall be that of the view displayed at the moment the animation is rendered.
This is the photorealistic rendering engine built in AutoCAD. It contains materials, lights ands shadows, etc.
When this renderer is selected, the user must set the desired rendering properties such as resolution, type of lighting, etc. using the AutoCAD dialog boxes.
Although normally the entire animation is rendered, Lands also allows the user to select an interval of frames.
Rendering only one interval is useful in cases where the user is forced to stop the rendering of the animation in the middle, when a system crash occurs and interrupts the rendering, etc. The user can ascertain at what point the process was interrupted by exploring the destination folder and the intermediate image files created, and resume the render from the last frame rendered.
