Features
Models
I got the model of the dragon from Blendswap and that of the cliff from
Turbosquid.
I duplicated the dragon model into three using Blender and adjusted them until I was satisfied with their positions on the scene.
I put together the dragons and the cliff and after some more adjustments I finally got the model I was opting for.
My model has 29664 faces. It is loaded as a .obj file and I have used BVH to intersect the model.
Codes: bvh.cpp, obj.cpp
Materials
-
Glass material. The water surface is a glass material both refracting and reflecting light.
Code: glass.cpp -
Lambertian and Combined materials. The sky and the moon are combined materials with an image texture and
a Lambertian material emitting some amount of light to give the scene a soft glowing effect. The grassy patch in front is also a combined material with
a grassy texture and a Lambertian material reflecting green color. It has some smooth rocks on it which are also Lambertian materials.
Code: combined.cpp, lambertian.cpp
Texture and Bump Mapping
-
Triangular mapping. It has been applied on the grassy patch, the sea, and the sky.
Code: tmapper.cpp -
Spherical mapping. The texture mapping on the moon is spherical.
Code: spherical.cpp -
Bump mapping. I used a bump map on the water surface to give me the desired ripple effect.
Code: bmap.cpp
Lighting
-
Point Light. Two point lights are used in the scene to give an indirect lighting effect
on the dragons.
Code: pointlight.cpp -
Area Light. A small area light has been cast on the scene from behind the camera, to get the desired silhouette effect on the dragons.
Code: arealight.cpp
Depth of Field
I added a slight depth of field effect,
to focus on the dragons and blur the grassy patch at the front of the scene.
Code: dofperspective.cpp
