CAVm4 - Moduloppgave

BIM Visualization

Interior visualization with advanced lighting.

For this modul exercise an existing revit model will be imported into Max. Advanced light settings will be used and furniture and materials will be also imported to make realistic interior rendering.

To start the exercise I imported the house from CAAm1 Module and used the second floor of the house. The file is sitting between Revit and Max.

After the import the first step is to place materials and lightning to the model

It is important to use natural light and also to have a roof on the model to have the correct light come through the windows

I made several attempts to perfect the amount of light in the room

The sun settings where finally placed as an actual time of day in a location in Norway so that the light would seem more natural. Interior lights were also included to have more complexity on the shadows and the lights of the model.

After having the correct balance of light I included mr. Sky portal featuresto have more light inside the rooms.

The next step is to include furniture and add more materials and textures to the room

I took furniture motels from the Internet, more specifically from sketch up.

Most of the important materials need to be adjusted in scale and texture to have a correct result. In most cases initially the material is not correctly scaled.

The process involves a lot of trial rendering and also selection of angles for the camera.

For the animation the Camera path is drawn and all the movements of the camera are programed using keys on the timeline. This is a very time-consuming procedure but it has very good results because there's good control over what the camera is doing.

For the final rendering of the pictures I selected the camera angles and also made some tests to know the correct amount of rendering time. I selected 6500 iterations for each of the pictures with resolution of 800 x 600 pixels.

Here is a picture of the living room looking towards the main windows

A picture of the kitchen and living room seen from thr dining place with the main windows on the back

A picture from the kitchen door showing good contrast between the natural light on the interior light

A picture from one of the rooms showing the intensity of the daylight as it comes through the window and also there's some good detail of the light at the other side of the house coming from the window near the staircase

For the panoramic picture I chose not to be placed at the center of the room but rather near one of the corners so that the best angles of the house are included in the panorama. The panorama picture was finally exported using QuickTime.

For the project plan my conclusion is that my estimate for the preparation of the model including import and setting of lights, interior furniture and textures was very accurate. However the time needed for rendering and animation was almost double as what I had estimated. This is mainly because I want to try else needs it to have a correct a camera angle and also setting the keys in the timeline.
