我正在尝试使用public async Task<IActionResult> LawFirmDetails(Lawyer lawyer) and the href to:
<a=href="~/Home/LawFirmDetails?lawyer=@info" class=header>First Name</a></th>
实现5x5卷积过滤器(查找边)这里是我的代码GLSL
来源:
.glsl
当我运行我的代码时,它给了我错误:
#version 150
#define SIZE 25
// A texture is expected
uniform sampler2D Texture;
// The vertex shader fill feed this input
in vec2 FragTexCoord;
// The final color
out vec4 FragmentColor;
float matr[25];
float matg[25];
float matb[25];
vec4 get_pixel(in vec2 coords, in float x, in float y) {
return texture2D(Texture, coords + vec2(x, y));
}
float convolve(in float[SIZE] kernel, in float[SIZE] matrix) {
float res = 0.0;
for (int i = 0; i < 25; i++)
res += kernel[i] * matrix[i];
return clamp(res, 0.0, 1.0);
}
void fill_matrix() {
float dxtex = 1.0 / float(textureSize(Texture, 0));
float dytex = 1.0 / float(textureSize(Texture, 0));
float[25] mat;
for (int i = 0; i < 5; i++)
for(int j = 0; j < 5; j++) {
vec4 pixel = get_pixel(FragTexCoord,float(i - 2) * dxtex, float(j - 2) * dytex);
matr[i * 5 + j] = pixel[0];
matg[i * 5 + j] = pixel[1];
matb[i * 5 + j] = pixel[2];
}
}
void main() {
float[SIZE] ker_edge_detection = float[SIZE] (
.0,.0, -1., .0, .0,
.0, .0,-1., .0, .0,
.0, .0, 4., .0, .0,
.0, .0, -1., .0,.0,
.0, .0, -1., .0, .0
);
fill_matrix();
FragmentColor = vec4(convolve(ker_edge_detection,matr), convolve(ker_edge_detection,matg), convolve(ker_edge_detection,matb), 1.0);
}
奇怪的是,当我试图在其他Linux上运行代码然后在Windows机器上运行时,它运行正常。此外,当我在Error Compiling Fragment Shader ...
ERROR: 0:17: 'texture2D' : function is removed in Forward Compatibile context
ERROR: 0:17: 'texture2D' : no matching overloaded function found (using implicit conversion)
Error Linking Shader Program ...
Attached fragment shader is not compiled.
Function is removed in Forward Compatibile context
函数中更改texture2D
以返回get_pixel()
时,它只会像魅力一样工作。有人可以解释问题出在哪里吗?

错误表示您需要知道的一切。 fit <- survfit(modform, data = ovarian)
fit$call$formula
# modform
fit$call$formula <- modform
fit$call$formula
# Surv(futime, fustat) ~ rx
fit
# Call: survfit(formula = Surv(futime, fustat) ~ rx, data = ovarian)
#
# n events median 0.95LCL 0.95UCL
# rx=1 13 7 638 268 NA
# rx=2 13 5 NA 475 NA
是GLSL 1.00天的旧功能。它被移除并替换为texture2D
,它使用函数重载来处理大多数采样器类型,而不是限制为texture
。因此,在核心配置文件或向前兼容性上下文中,您无法调用sampler2D
。
