Question 16 1 points Save Ang _ if all points on the line segment between any two points inside the object, or on its boundary, are inside the object. Question 17 Which of the following code segment will make the window solid and red? O gl.clearColor(0.0, 0.0, 1.0, 1.0); g1.clear(gl.COLOR_BUFFER_BIT); gl.clearColor(1.0, 0.0, 0.0, 1.0); g1.clear(g1.COLOR_BUFFER_BIT); gl.clearColor(0.0, 0.0.0.0, 1.0); g1.clear(gl.COLOR_BUFFER_BIT); o gl.clearColor(0.0, 0.0.0.0, 0.0); g1.clear(gl.COLOR_BUFFER_BIT); o gl.clearColor(0.0, 1.0, 0.0, 1.0); g1.clear(gl.COLOR_BUFFER_BIT); Question 18 1 points Save Answer A viewport is a rectangular area of the display window. By default, it is the entire window, but it can be set to any smaller size in pixels via the function gl.viewport. In following function call, what is the width of the viewport? gl.viewport(1, 2, 3, 4); 0 0 0 0 Question 19 Consider a minimum GLSL fragment shader: precision mediump float; void main({ gl_FragColor = vec4(1.0.0.0, 0.0, 1.0); This shader will make the displayed point translucent. True False Question 20 Select code that will be put into a simple render function that will display a sequence of triangles. gl.clear(gl.COLOR_BUFFER_BIT); gl.drawArrays(gl.POINTS, O, numPoints); gl.drawArrays(gl.TRIANGLES, O, numvertices); gl.drawArrays(gl.LINES, O, numVertices) points.push(a)
