The spherical lens computes equirectangular images. These
images with a strange look have always a height equal to the
half of their width (2/1 proportions) and are useful to generate
a panorama viewable with Quicktime VR, JavaScript tools
like Panolens or Three.js,... |

In the Lights category of the catalog, there are
some special lights called Light source and represented
by a light bulb icon. These light sources have no physical 3D
representation and can be seen in the 3D view only when selected,
for feedback purpose. They are used only to enlighten the 3D
view at the two best quality levels. Enlarging them will produce
softer shadows. |
|
At the two best quality levels, the color of the sun rays
depends on the elevation of the sun in the sky at day time,
and the sun doesn't produce light at night time. If you selected
a color for the sky in the 3D view
pane or if the current mode is Aerial view, a sky image
computed according to the hour of the day is used for the rendering
of the sky. If you chose a texture for the sky, that texture
will always be used in Virtual visit mode whatever the
selected hour. |
|
If the computed image is all black, check whether the virtual
observer is in a wall or not, and at night time, if there are
some visible lights with a power greater than zero or if Add
ceiling lights check box is selected. If the hour you entered
is an hour of the day, check
also if the geographical location and the time zone are consistent.
Remember that when it's midday in Central European Time zone,
it's still night time in California.

In Aerial view mode, the ceilings of the rooms are
not seen. If you want to see them at the best two quality levels,
you should use Virtual visit mode and elevate the point
of view of the virtual visitor. |
|
At a given quality level, you can still improve the image
quality by choosing a bigger size for your image, then reducing
the size of the computed image in an editor like The Gimp. |
|
At the two best quality levels, the Renderer
dropdown list lets you choose the rendering engine that will compute the
image (not available on all systems). If you want to render images more quickly,
try YafaRay and / or turn off some useless lights. An image of larger
dimensions will also take more time to be computed. |
|
The Create photo and Create photos at points of view dialog boxes aren't modal. This means
that it doesn't block the input in other windows and lets you
modify your home or your point of view in the main window, while one of
these dialog boxes is opened. |
|
While a photo a is computed, changes made in your home
won't affect the current rendering. |
