Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 6 jgs mesh.h | cube texture

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 7 jgs mesh.h | skybox texture

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 8 jgs render.h § GLuint meshToDisplayList(Mesh* mesh, int id, int texture) § glNewList(listID, GL_COMPILE); § glEnable(GL_TEXTURE_2D); § glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); § glBindTexture(GL_TEXTURE_2D, texture); § glBegin(GL_TRIANGLES); § for (/* for each triangle in a mesh */){ § // normal § // texture § // color § } § glEnd(); § glDisable(GL_TEXTURE_2D); § glEndList();

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 9 jgs controls.h § float camera_x = 0.0; § float camera_y = 300.0; § float camera_z = 320.0; § float camera_viewing_x = 0.0; § float camera_viewing_y = 301.0; § float camera_viewing_z = 0.0; § float total_moving_angle = 0.0; // gluLookAt( camera_x, camera_y, camera_z, // camera_viewing_x, camera_viewing_y, camera_viewing_z, // 0.0f, 1.0f, 0.0f // );

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 10 jgs Moving the Camera as a First Person Walk § Look up and down § Rotate Left or Right § Move forward or Backward

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 11 jgs Up and Down § Look UP camera_viewing_y += (10); § Look DOWN camera_viewing_y -= (10);

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 12 jgs Rotate Left and Rotate Right § Move LEFT total_moving_angle += -0.01; rotate_point(-0.01); § Move RIGHT total_moving_angle += 0.01; rotate_point(0.01);

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 13 jgs Front and Back § Move FRONT camera_x += (10) * sin(total_moving_angle); camera_z += (10) * -cos(total_moving_angle); camera_viewing_x += (10)* sin(total_moving_angle); camera_viewing_z += (10)* -cos(total_moving_angle);

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 14 jgs Quiz 01 Solution

Javier Gonzalez-Sanchez | SER431 | Fall 2018 | 15 jgs Quiz 02 § // Lava / fire texture around the space to avoid get closed to the walls § // Terrain at the center. Add altitude to the pain with stone texture § // What about making a cube able to move (rotate or something). // But, the terrain will not be plain (it is a non-flat surface)
