Подскажите как наложить текстуру name.TIF на мою модель?
Считал файл с изображением и поместил его в буфер для изображения:public static ByteBuffer loadTexture(String path) {
BufferedImage image = null;
try {
InputStream in = new FileInputStream(path);
image = ImageIO.read(in);
} catch (IOException ex) {
throw new RuntimeException("Failed to load a texture file!"
+ System.lineSeparator() + ex.getMessage());
}
if (image != null) {
AffineTransform transform = AffineTransform.getScaleInstance(1f, -1f);
transform.translate(0, -image.getHeight());
AffineTransformOp operation = new AffineTransformOp(transform,
AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
image = operation.filter(image, null);
int width = image.getWidth();
int height = image.getHeight();
int[] pixels = new int[width * height];
image.getRGB(0, 0, width, height, pixels, 0, width);
ByteBuffer buffer = BufferUtils.createByteBuffer(width * height * 4);
for (int y = 0; y < height; y++) {
for (int x = 0; x < width; x++) {
int pixel = pixels[y * width + x];
buffer.put((byte) ((pixel >> 16) & 0xFF));
buffer.put((byte) ((pixel >> 8) & 0xFF));
buffer.put((byte) (pixel & 0xFF));
buffer.put((byte) ((pixel >> 24) & 0xFF));
}
}
buffer.flip();
return buffer;
} else {
throw new RuntimeException("File extension not supported!"
+ System.lineSeparator() + "The following file extensions "
+ "are supported: "
+ Arrays.toString(ImageIO.getReaderFileSuffixes()));
}
}
Класс, отвечающий за рендеринг модели(максимально сократил), строит по треугольникам модель из obj файла:private final int vaoTriangles;
private final int shaderProgram;
private ObjModel objModel;//модель обж файла
SceneRenderer(ObjModel objModel) throws Exception {
this.objModel = objModel;
glEnable(GL_DEPTH_TEST);
glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
glPointSize(10);
String fragmentSource = IOUtils.toString(getClass().getResourceAsStream("shader.frag"));
String vertexSource = IOUtils.toString(getClass().getResourceAsStream("shader.vert"));
shaderProgram = Util.createShaderProgram(vertexSource, fragmentSource);
int vertexBuffer = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer);
glBufferData(GL_ARRAY_BUFFER, Geometry.objFileObject(objModel).rewind(), GL_STATIC_DRAW);
int normalBuffer = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, normalBuffer);
glBufferData(GL_ARRAY_BUFFER, Geometry.getNormals(objModel).rewind(), GL_STATIC_DRAW);
vaoTriangles = glGenVertexArrays();
glBindVertexArray(vaoTriangles);
glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer);
glVertexAttribPointer(vertexLocation, 3, GL_FLOAT, false, 0, 0);
glBindBuffer(GL_ARRAY_BUFFER, normalBuffer);
glVertexAttribPointer(normalLocation, 3, GL_FLOAT, false, 0, 0)
glBindBuffer(GL_ARRAY_BUFFER, 0);
glBindVertexArray(0);
}
void render() throws Exception {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // clear the framebuffer
FloatBuffer vMatrix = BufferUtils.createFloatBuffer(16);
new Matrix4f()
.lookAt(cameraPosition.x, cameraPosition.y, cameraPosition.z,
0.0f, 0.0f, 0.0f,
0.0f, 1.0f, 0.0f).get(vMatrix);
FloatBuffer mMatrix = BufferUtils.createFloatBuffer(16);
new Matrix4f().translate(modelPosition)
.rotateX(modelRotation.x)
.rotateY(modelRotation.y)
.rotateZ(modelRotation.z)
.get(mMatrix);
glUseProgram(shaderProgram);
glUniformMatrix4fv(glGetUniformLocation(shaderProgram, "P"), false, pMatrix);
glUniformMatrix4fv(glGetUniformLocation(shaderProgram, "V"), false, vMatrix);
glUniformMatrix4fv(glGetUniformLocation(shaderProgram, "M"), false, mMatrix);
glUniform3f(glGetUniformLocation(shaderProgram, "light_worldspace"), lightPosition.x, lightPosition.y, lightPosition.z);
glBindVertexArray(vaoTriangles);
glEnableVertexAttribArray(vertexLocation);
glEnableVertexAttribArray(normalLocation);
glDrawArrays(GL_TRIANGLES, 0, objModel.getIdx().size());
}
}
Ну и фрагментный шейдер, в котором происходит заливка цвета:#version 330 core
in vec3 normal_modelspace;
in vec3 vertex_modelspace;
out vec3 color;
uniform vec3 light_worldspace;
void main() {
vec3 n = normalize(normal_modelspace);
vec3 l = normalize(light_worldspace - vertex_modelspace);
float cosTheta = clamp( dot( n, l), 0,1 );
float ambient = 0.05;
color = vec3(0.0,1.0,0.0) * (cosTheta + ambient);
}
