Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 2 jgs Viewports § Divide the screen in two vertical view ports § Or, add a second viewport to show the score of a game
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 3 jgs OpenGL § Write a short programming segment that draws the triangle fan shown below. You do not have to worry about setting projections, opening windows, setting the camera, transformations, …. Just the code to draw the triangle fan. Make sure triangles are in counterclockwise order (0,1) (-3,3) (-1,5) (1,4) (3,2)
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 5 jgs Vector Programming § Given the arrays vec3f vertices[NUM_VERTICES]; // float vec3i indices[NUM_TRIANGLES]; // integer § Write a procedure that returns the per-face normal vector for a face with number index vec3 computeFaceNormal(int index) { }
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 6 jgs Vector Programming § Given the arrays vec3f vertices[NUM_VERTICES]; // float vec3i indices[NUM_TRIANGLES]; // integer § Write a procedure that returns the per-vertex normal vector for a vertex with number index vec3 computeVertexNormal(int index) { }
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 7 jgs Mesh Data Structure Define a mesh data structure able to store: § vertex/faces, § normals per face, and § texture coordinates. You worked with one like this in your project 4.
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 8 jgs Mesh Data Structure § Store values in the mesh data structure to define a right-angled triangle at coordinates [0, 0, 0]. Legs are aligned to axis X and Y, respectively. Its length is 50.
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 9 jgs Textures § Given the BMP image shown below. Store values in the mesh data structure to apply a texture to the triangle defined above and make it looks like shown in the second image below BMP file Model
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 10 jgs Textures § Create a display list for a cylinder using triangles with a texture as done in the previous question.
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 11 jgs Materials § Write the code to create a triangle that has the highest emissive values. It should be the brightest object in any scenario.
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 13 jgs Materials § Is the shininess value for chrome greater than or lower than rubber? __________________ § Are the diffuse constants for pearls greater than or lower than plastic (black)? __________ § Are the specular constants for metals greater than or lower than pearl? ________________
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 14 jgs Navigation § Make the camera move autonomously from point A to point B. Given that the method scenario() return a display list with the four buildings described below. Buildings are 100x100x100 units
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 16 jgs Animation § Move the spaceship using the keyboard § Move asteroids randomly § Move ufo around the screen
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 17 jgs OpenGL § What does OpenGL stand for? § What does GLU stand for? § What does GLUT stand for? § Give three OpenGL commands as example?
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 19 jgs Linear Algebra § Given three vertices of a triangle (v1, v2, v3), how can you compute the normal vector for v2?
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 21 jgs Fonts § Give one advantage and one disadvantage of a bitmap font. § Give one advantage and one disadvantage of an outline font.
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 22 jgs Frame Buffer How many bits does a frame buffer need for: § 1024 x 768 resolution § RGB values and alpha values and 8 bit z- buffer How many bytes does a frame buffer need for: § 1000 x 1000 resolution § RGBA values § Double buffering
Javier Gonzalez-Sanchez | SER332 | Spring 2018 | 23 jgs OpenGL § Write the glut command to request a display mode that has: double buffering and RGBA color values. § Write the glut command to request a display mode that has: single buffering and RGB color values
