ASA Architectural Presentation Workshop
Presented by Feargal Foley
Programmes used..... AutoCAD or Sketch Up 3DS Max Photoshop Illustrator also possibly
Goals Create and image that is.... Real but not too real Achieve depth using line, texture, shade and tone
“School of Athens� by Raphael 1506
STAGE 1 Create a Model - Be strict with layers. Each building fabric/skin should be a new layer. - Think of how you construct the model. It might tell you something about how you build a building. - You can use the model for more than just renders. I.e construction drawings.
To set up Camera in CAD Type “Camera� Click camera location and target and click enter. Click on the camera to move it or the Target to move the target.
Properties
Lens Length
To set up Camera in CAD - Click properties, and set the “lens length” type you wish. - Type “View” and click on “camera 1” and “set to current” - Print to PDF from Model space with the visual style set to hidden - SAVE THE DRAWING WITHOUT MOVING THE CAMERA!!!!
Sketch Up Pro - In Sketch up Pro set up a scene and save the file - Export the view to pdf. Click “File”, “Export”, “2D Graphic” - Export the model Click “File”, “Export”, “3D Model” File Type “.3DS”
STAGE 2 Create Realistic lighting
Open 3DS Max Import the CAD File – Click “File”/”Import”....select CAD file Ensure “Derive AutoCAD primitives by” is set to entity Ensure “Include” is set to views and cameras only. Click OK.
Selection Tool
Standard material
Select Everything
STAGE 2 Create Realistic lighting
Add A White material - Click “M” and up will pop some materials - Select everything. - Click on a white paint like standard material and click “assign material to selection” - Now the Model is white.
Systems Select Top View Move Scale Daylight
STAGE 2 Create Realistic lighting Realistic Lighting Click The “Top View” Click “Systems” Click “Daylight” A pop up box will appear asking you if you want mr Photographic Exposure Control....click yes. Click anywhere in the “top view” window Click Yes to the pop up window asking you if you want a mr Physical Sky Moving the mouse will move the sun. Just set it anywhere you like. On the right hand side you can adjust the sun's angle by time, date and location.
Quick Render
STAGE 2 Create Realistic lighting
If we click render now we will get a realistic rendering as if the model was made of clay. The structure is set in a forest however and I want to cast shadows of some foliage.......
Create Geometry Drop Down Menu
Foliage
STAGE 2 Create Realistic lighting Create a tree: - Click “Create” - Click “Geometry” I- n the drop down menu click “AEC Extended” - Click “Foliage” - Pick a Tree and place it in the “Top Plan Window” - Use the “Uniform Scale” tool to scale up the tree. - Set it to a large enough size and position it using the “move tool” so that it casts a good shadow across two planes of the structure.
Render Set Up Box
Render Button
STAGE 2 Create Realistic lighting
Rendering: - Click the Render set up box - Under the “Common Tab”, set the “Output Size” to something like 1600 wide by 1200 high - Click Render.... This may take some time! Best leave the PC alone while it renders. - Save the image as a JPEG when its done. You're Finished with 3DS Max
Polygonal lasso
STAGE 3 Photoshop Lay 3D Max image behind line drawing
Photoshop - Open the pdf line drawing of the model in Photoshop at 300dpi - Set another layer behind it and “bucket tool� it white so that you can see what you are doing. - Open the 3DS Max lighting study jpeg copy and paste it in laying it behind the line drawing. - Scale it to suit (Control T). A little tweaking might be required with perspective. - With the polygonal lasso too cut out everything except the structure and the shadow cast by it.
Gradient Tool Run the gradient in this direction
STAGE 3 Photoshop
Making the cliff face - Bring in the cliff face and set it behind the line drawing. - Using the scale and perspective (Control T and right click on the layer) transform tools place it as shown. - Use the gadient too to fade out the top of the cliff to white (see next slide) - Trim it with the polygonal lasso tool if required. - Under “layer� bring the opacity back to around 70%
Multiply
STAGE 3 Photoshop Layer Tab Drop Down Menu
Now place it behind the 3DS Max light study layer. Notice the shadow cast on the cliff by the structure is solid grey. Click the 3dS Max light study layer and under the layers tab click multiply on the drop down menu. This makes the layer transparent as if on printed on perspex. The cliff now appears where the structure is so cut it out using the polygonal lasso tool.
STAGE 3 Photoshop
Applying the Ply - Copy an image of plywood or OSB. - Use the perspective transform tool to orientate the board approximately to a single sheet on the CAD drawing. - Trim around it using the polygonal lasso tool. - Repeat until the structure is covered and merge all these layers together. (to merge layers sellect them all by holding control and then press “control + E�) - You can now adjust the opacity of the plywood layer and 3DS Max shading layer to suit yourself.
Brush Drop Down Menu Brush Size Hair/Grass Brush
Brush Tool
STAGE 3 Photoshop
Planting the Grass: - Set up a new layer - Click “brushes” - On the “brush shape drop down menu” find the grass or hair like brush and set the size fairly big. .
STAGE 3 Photoshop
Planting the Grass: - Start from the foreground and moving across parallel to the cliff create two lines deep of grass - As you move away from the camera stand point decrease the brush size to create a feeling of perspective. - Then create a new layer and slightly behind the first line of grass create a new line with a slightly smaller brush. - All the time we are creating perspective here with the texture of the grass. - Reduce the opacity of this layer to say 90%. Again this creates perspective. - Repeat this process until you get to the top of the hill at say 50% opacity. Merge these layers.
STAGE 3 Photoshop
Planting the Trees: - On the project file there will be some tree brushes in the brushes folder. - These need to be coppied into the brushes folder where photoshop is installed most likely located here: C:\Program Files\Adobe\Adobe Photoshop CS3\Presets\Brushes
Brush Tool
STAGE 3 Photoshop
Planting the Trees: - Create a new layer and call it “Trees 1” - Click “Brush” and click on some trees you like and place them on the drawing. - Use different trees and trees of different sizes by changing the brush size. 3 or 4 trees will do at this stage. - Cut out the trees where they overlap with the structure so that they appear in the backgroung.
Layer
STAGE 3 Photoshop
Planting the Trees: We want to make these trees look far away so we want them to look really light - Click “layer”, Go to “Layer Style”, Click “Colour Overlay” - Set the colour to white and the opacity to 80% - Click “Ok” and the trees appear faint - To create trees closer to the fore ground create a new layer, place new trees and repeat the same steps except this time set the opacity of the overlay to say 50% and another layer of trees for 35%.
STAGE 4 Clean Up
To clean up: Click on the CAD line drawing layer and using the polygonal lasso tool cut out any unwanted lines like for example the generating lines CAD produced for the cliff. Adjust any layer opacities to suit printing/publication etc.
And that’s it you’re done !!!
