Thanks, I think I can figure most of it out from here. I am new to VES, so I wonder what is the reasoning for encapsulating the functionality I need in a class vesBackground::vesInternal, thus hiding it from the headers and documentation?<br>

Hi Jurre,<br>
<br>
You will have to add blend attribute as well (vesBlend). The default blend<br>
equation probably will work for you. Have a look at the vesBackground.cpp.<br>
Let us know if you need any help.<br>

Hi,<br>
<br>
I am developing an app based on the KiwiViewer code. Objects should be<br>
rendered on a transparent background instead of the standard blue one, such<br>
that another Android layer (a camera view, in this case) can be displayed<br>
behind it.<br>
<br>
To achieve this, I have modified the function declaration and definition<br></div>
of vesKiwiBaseApp::**<u></u>setBackgroundColor() such as to expose the<br>
alpha-argument of vesRenderer::**<u></u>setBackgroundColor():<br>
<br>
void vesKiwiBaseApp::**<u></u>setBackgroundColor(double r, double g, double b,<br>
double alpha)<br>
{<br>
this->Internal->Renderer->**<u></u>setBackgroundColor(r, g, b, alpha);<div class="im"><br>
}<br>
<br>
In KiwiNative.cpp, I can now call app->setBackgroundColor() as follows:<br>
<br>
bool loadDataset(const std::string& filename, int builtinDatasetIndex)<br>
{<br>
// ...<br>
app->setBackgroundColor(255, 0, 0, 0);<br>
// ...<br>
}<br>
<br>
Alas, this changes the background color to solid red instead of<br>
transparency.<br>
<br>
How to achieve rendering on a transparent background with Kiwi?<br>
<br>
Regards,<br>
Jurre<br></div>
