In todayโs blog, lets uncover some of the methods of Visualization SOLIDWORKS
has to offer, take a more in-depth look at RealView, and then weโll take a
look at which option will suit you best!
The first visualization technique that doesnโt require any special hardware
will be OpenGL. All modern graphics cards have OpenGL capabilities, and should
be able to handle OpenGL. All the processing is normally done on the Graphic
Processing Unit (GPU).
Next, if youโre looking for more a realistic rendering, RealView will build
off of what OpenGL provides. Now, if youโre not seeing RealView, which is
found under โView Settingsโ in the โHeads Up Toolbarโ, youโll want to make
sure that โSoftware OpenGLโ is not turned on. The easiest way to identify if
it is, is by going to your โSystem Optionsโ > โPerformanceโ > making
sure โUse software OpenGLโ is not checked, as seen here. What software OpenGL
does, when enabled, is disables the graphics card hardware accelerator and
enables graphics rendering using only the software. Note that if you do have
it turned out, youโll have to close all existing files to be able to uncheck
โUse software OpenGLโ since it is a โSystem Optionโ and isnโt
document-specific.
If youโre still not seeing RealView after verifying OpenGL is not on, youโll
want to make sure you have an approved graphics card as well as the best
graphics card driver for the software version youโre running. You can navigate
here to the SOLIDWORKSโ website:
www.solidworks/sw/support/videocardtesting.html, where youโll simply just put in the model of your workstation or locate the
specific graphics card you have. You can then download the driver and see if
โRealView Graphicsโ becomes available for you!
The benefit of activating RealView is it will generate more of a realistic
image by including:
- Dynamic and environmental reflections such as ground
- Surface shading including color, ambience, diffusion, and transparency
-
Basic texture mapping techniques,, such as visible bump surface finish
(depending on material/appearance applied) - Diffused ground shadow
- Self-Shadows from the first directional light
When we begin to compare RealView to PhotoView 360, RealView only casts a
self-shadow and floor shadow for the first directional light. You can easily
adjust the directional light by going first to your โFeatureManagerโ, clicking
on the last tab for the โDisplayManagerโ > โView Scenes, Lights, and
Camerasโ > expand out the โLightsโ folder, and right-click the
โDirectional1โ to get โEdit Directional Lightโฆโ
Lastly, how does RealView stack up to PhotoView360? PhotoView360, a SOLIDWORKS
Professional add-in, allows for more in-depth, photorealistic renders and we
can begin to see the differences between RealView and PhotoView 360 based off
the chart below:
If you take a look below, I have three samples of the visualization we talked
about today: OpenGL, RealView, and PhotoView 360.

The main advantage of OpenGL is the ability to take a quick snapshot and is
the fastest of the three visualization methods. The disadvantage, as you can
see, would be that it contains the least amount of detail of the three. The
advantages RealView has over PhotoView 360 differences lie in processing time
and the ability to render during motion. With RealView, you can rotate and pan
around your model and the model will retain of the RealView characteristics.
With PhotoView 360, the โFinal Renderโ window will only capture statically
what it sees in the window, which means any changes to the camera position or
model must be rendered again. In addition to that, PhotoView 360 requires more
processing time, but it can be scheduled when youโre away from the computer or
off from work! PhotoView 360โs advantages are that itโll provide the most
realistic render of the three, while providing more options in terms of light
sources that influence shadows, depth of field, and advanced texture mapping.
At the end of the day, as long as you have SOLIDWORKS Professional or Premium,
the beauty is you really donโt have to choose. As you can see, SOLIDWORKS
makes it incredibly flexible for you to generate all three outputs to see
which one will give you the desired outcome!
I need to run my Solidworks in GL mode as my graphics card, and my computer don’t meet the levels needed for Solidworks. I appear to be able to get it to run in open GL mode. My question is I am I getting all the features of Solidworks just not the shadows, and shading running in GL mode? I have just started using the product, and am teaching my self.
