大家好，我的着色器片段和顶点有很多问题。我不确定我真正想念的是什么，任何帮助都会很棒。到目前为止我的代码我得到了这个！ https://www.dropbox.com/s/7qgl6h2d3p3klu0/Screenshot%202015-05-02%2015.02.50.png?dl=0
但它假设看起来像这样，我错过了什么？ https://www.dropbox.com/s/uy6093tbdtmcdux/Screenshot1.jpg?dl=0
这是我的代码片段代码：
#version 150
in vec3 fN;
in vec3 fL;
in vec3 fE; // NEW! Coming in from the vertex shader
out vec4 fColor;
void main () {
vec3 N = normalize(fN);
vec3 L = normalize(fL);
vec3 E = normalize(-fE); // NEW! Reverse E
vec3 H = normalize(L + E); // NEW! Create the half vector
// Diffuse component
float diffuse_intensity = max(dot(N, L), 100);
vec4 diffuse_final = diffuse_intensity*vec4(0.0, 0.0, 2.8, 2.0);
// NEW! Specular component
float spec_intensity = pow(max(dot(H, L), -1.5), 60);
vec4 spec_final = spec_intensity+vec4(0.0, 0.0, 2.8, 2.0);
fColor = diffuse_final + spec_final;
}
这是我的顶点代码：
#version 150
// Combined our old stuff with the shader from Angel book
in vec4 vPosition;
in vec4 vNormal;
uniform mat4 mM; // The matrix for the pose of the model
uniform mat4 mV; // The matrix for the pose of the camera
uniform mat4 mP; // The perspective matrix
uniform mat4 mR; // The rotation matrix
uniform vec4 lightPosition; //
out vec3 fN;
out vec3 fL;
out vec3 fE;
void main () {
fN = (mR*vNormal).xyz; //Rotate the normal! only take the first 3 parts, since fN is a vec3
fE = (mV*mM*vPosition).xyz;
fL = (lightPosition).xyz; // In world space
gl_Position = mP*mV*mM*vPosition;
}
